VR commodore wont start??

Ok I jumped into my VR commodore the other day and went to the supermarket locked it and done my shopping, I came back to my car an hour later and unlocked it and it wouldnt start, well started at first and then stalled, I couldnt hear the fuel pump whirring so I thought it was stuffed, so I called a tow truck and took it home, I tried starting it the next day( it hadnt been locked) and it still wouldnt start, so yesterday I was outside again and thought Id give it another go and it started, today I drove it to the supermarket and left it running while I done what I had to do and was fine, then I drove home turned it off and tried starting it and it worked then i tried locking and unlocking and it wouldnt start, anyone know whats wrong?? PS when it wouldnt start it would still turn over but couldnt hear the fuel pump whirring.

commodore not starting

i'm not sure of the proper way of testing a fuel pump (if there is one), but this is how i do it,
first make sure the ignition is off, take the fuel line off where it goes into the fuel rail and put the fuel line into a old bottle or tin, then get a helper to turn the ignition to the on postion, if the fuel pump is working then fuel will come out

i'm don't know to much about commodores but the fact that it goes sometimes and not others doesn't sound like a fuel pump to me

a common problem for not starting in these models is the crank angle sensor

cheers dave

my vr brelina

i pulled out the engine n box replaced the seals and 2500 dollars later its wont start n if it does it stalls the fuelpump works fine n some times it blows the air box up

VR No Start

Not Sure if you have a V6 or V8?

If it's blowing up the air box it sounds like either the plug leads are not in the right sequence ( 6 And/Or V8 ) or the Timing is way out ( V8 probably the distributor 180 degrees out of index )

The more info you can give us will help with a solution !

Ignition Key Battery

Isn't this another one of those Ignition Key Battery going flat deals?

I've seen it in other cars. The Engine will crank but not fire.

couldnt hear the fuel pump

It sounds like you are having a problem with the imobiliser part of the sercurity system.
IIRC there is a key switch on the door jam when you open the passenger side door.
It may need to be reset.
Note: I don't know very much about VRs. So I may be quite wrong.

would the crank angle sensor

would the crank angle sensor stop the fuel pump working tho?

crank angle sensor

I wouldn't think so.
When the ignition is turned on the fuel pump should run for a few seconds regardless of the crank sensor.
If there is no action at the fuel pump for a few seconds when the ignition is first turned on, it will be the imobiliser.
Cheers.

i just had a look at my car

i just had a look at my car a minute ago and the red imobilisor light was flshing with the car unlocked, it stopped when i turned the ignition on, still wont start

VR doesnt have a reset key

VR doesnt have a reset key switch:(

VR wont start

We are having the same problem with our VT the battery in the key is nearly stuffed, so we unlock the door with the key (novel way to do it) and occasionally it still wont start so we push the boot release button on the key and this turns the immobiliser off and the car starts.

I think from memory the

I think from memory the keypad can be seperated.(I think VS ones can't be seperated as easy).
They have a metal plate, which holds the battery and makes contact with the circuit board.
They get a dry solder join there.
Resolder and see what happens.

no start

I'm pretty sure you will have to get another key head? When locking your car, lock it with the key and not the buttons. This then will not activate the immobilizer, so you should then be able to start it.I have heard if you leave the ignition on for 30 to 40 minutes or longer, it deactivates the immobilizer and the car will start.

tried leaving ignition on

tried leaving ignition on for 30 mins - no go, looked at solder in the key and still looks good

Fuel pump

It could be the immobiliser as stated above, but Id say your Fuel pump is stuffed, its typical symptoms for an electric fuel pump. They will work on occasion, then wont work, unpredictable really, when its not working, you can thump on the bottom of the tank either with your fist or a rubber mellet, and see if you can shock it enough to start working again.

Intermitant nightmares

Is it a 5L or a six?, cos I had the same problem with my VS 5L calais.
If you have a 5L it is probably your dizzy. The injector pulse comes from the dizzy in injected V8s as opposed to the crank angle sensor in 6s. Exactly the same problem though, sometimes it would start, sometimes it wouldn't. It took me months to find it. It threw me cos it had spark and fuel pressure, but I wasn't educated about injector pulse.
Keep in mind aswell that once your fuel system pressurises, your pump will automaticly cut out. this could explain why you can't hear your pump. It should go for a second or 2 when you first turn your ignition on.
If your car is in fact a 5L, have lots of fun changing your dizzy, you WILL swear, you WILL cry and you WILL lose skin.

Ute vs v8 stopping and won't start !! Random

Hi lads I got a vs 5.0 lite manual and had same problems gave it to sparky as I was flatout as im a diesel fitter and didnt have time due to work alas all they did was replace parts spark booster battery terminals I said check pump they didn't I said what about immobiliser they didn't check I paid them for some work but after 3 tows and several returns I said piss off it
sat it at my house till I had time to check I replaced fuel pump as it wasn't priming and it started straight away but stopped I found the immobiliser was acting up with intermittent issues I did make sure it was disabled and replaced battery in key and it works perfectly fine and ute hasn't stopped since

lol not a 5L luckily, I

lol not a 5L luckily, I checked the fuel line near the injector rail and it had no pressure. What does the immobilisor immobilise?

i'll try giving the fuel

i'll try giving the fuel tank a thump but Im still thinking its the immobilisor seeing as it done it after I locked/unlocked the car.

immobilizer

The Immobilizer usually cuts the injectors out, the fuel pump should still work. Still wouldn't go past the crank angle sensor either?

Can any one tell me how to

Can any one tell me how to change crank angle sensor?

crank angle sensor

My '94 VR V6 would not start two days ago after its second supermarket stop on the way home from a fairly long drive. The ignition started then it cut out. Several attempts and NRMA patrolman did not work. Problem, as divined by my regular mechanic after about a day of testing turned out to be the crank angle sensor.

I hope this can be of help to some of you.

The saga continues....

If you can lock and unlock your car with the keyless remote, I doubt there'd be anything wrong with the immobiliser.
Make sure that you have spark and listen to make sure that the injectors are clicking when you wind it over. if you have both of those and no fuel pressure, I'd say your pump is pregnant.
If your injectors are not clicking, crank angle sensor.
After saying all of that, I'm not a mechanic and I'm only guessing, but most mechanics just replace stuff till they jag it anyhow. They've just got a better idea of where to start looking. No offence to the mechanics out there (but you know it's true ;))

ok so I gave the fuel tanks

ok so I gave the fuel tank a few hits with a mallet, turned ignition on then heard fuel pump (sounded different) it started then ran a little then stalled, another tap and started and didnt stall drove down to the shop and back and is running a little wierd and smells very rich (fumes burn my nose) so its the fuel pump?

Sounds like it........

..... but no idea what the fumes would be, could be unrelated?

If you replace the pump, either shop around or get one off ebay, from memory they are only 70 bux for a Delphi one (which Im pretty sure is the OEM for holden anyway) yet Holden wanted over 400 bux.

vr wont start

I have had a vn,vp,vr,vx without any of these problems, but my vy does exactly the same, and I find if i relock the car, even with the key in or out of the ignition,and then try again it works 98% of the time. they tell me it is something to do with the knob on the key is not connecting properly with its mating part in the ignition switch.The car will start but the security system does not recognise the key and shuts it down.Mine has been on the computer diagnostic and it tells me this is the problem.

I got a VS ute and the same

I got a VS ute and the same thing is happening. It runs fine in the morning, but after work it it dies in the arse after about 10mins. I starts again if I leave it for a bit.

A friend is a holden mech, he reckons it's the crank angle sensor. If it stops, pour a bottle of water over the engine too cool it down a bit.

REPCO are chaging $96, and SCA $81 for new ones.

ive got a vr 5L a few days

ive got a vr 5L a few days ago it cut out on me at an intersection, after getting it home and had a look i figured it was a fuel pump as i couldnt hear it prime. after changing the pump it still wouldnt start. turns out im blowing the engine fuse as i start it so i figure shorting out somewhere? i disconected the alternator and had to jump start it. it got up and going but died about 5minutes later as the engine fuse had blown again...... what else should i look for cause its got me stuffed

engine fuse

could it be something to do with the wiring when you put the new pump on?? maybe put up a new post so more ppl can see your question rather than hijack a thread

thanks, Hayden

I got a lot of joy from this thread,

what you all really need is a red 308, & a 3 speed column change box. Failing that, a 186 would solve the issue. If you are really game, maybe even a grey 138 would improve the situation....

VR 94 COMMODORE KEY AND START PROBLEMS

I have a 94 model VR Commodore. Lost the only set of keys i had, went to Holden, got the code took the code to a locksmith, i paid $150 to get the key cut. i get home and charge the battery (it has been sitting in the driveway for 4 weeks) put the key in and it turns on all the lights and everything but does not start or kick over or anything. i dont know what the problem would be???

vr won't start

i have a vr commodore that wont start. the battery is new termanals are new. you turn the key and get lights on the dash fuel pump comes on. but you turn it to start lights go off motor won't turn or crank i know it sound like a battery but its not. what is please help thanks tim...

vr wont start

your stater moter is dead put a new one in & it will be right

try this

i didnt read all the posts there where too many and im a lazy fart but for the original post its most likely the pump as when he banged the tank it worked than didn't work.VEry common seen it heaps of times.
1] fuel pump won't run all the time so turn the reds on and get a mate to put an ear to the tank to hear the pump. the pumps work on pressure and will switch off once it hits is desired pressure. if it don't work then it could be fuse, relay or stufffed pump.most common causes.but like old mate leave the reds on and bang the tank if it works after a love tap then its stuffed replace it.
2] if you think its the crank angle sensor which it does sound like cause they will play up and then work then play up [ like fuel pumps], get the hose, yes the hose and carefully not to put water anywhere else with low pressure put it in a position where the stream hits the crank angle sensor[ just right about half inch, and behind the harmonic balancer then try to start it. if it start with the cold water on it and not after you let it sit and dry off and get hot, then its the crank sensor. [try starting before you use the water you won't narrow down the problem if its not occuring.
it is possible it could be a combination of both these things but i would start with the pump.

vr hard to start and auto not changing till it hits 4 to 5ooo

VR V6 having starting problems - PLEASE HELP

Hey guys, i have a 94, VR V6 commodore and i'm having problems with starting it and hopeing that theres someone who can help me. After connecting the scan tool to my car the only code it comes up with "HOT WIRE CONDITION - immobiliser" and it wont allow me to erase it, how can i fix this?

Like a lot of other post that i've read my car will only start after 1hr (when the key is turned to on pos. - after it has by passed the immobiliser). Has anyone had any issues with there immobiliser, and can anyone please tell me where the B.C.M is?

Thanks people, Sharwood

Plus one more thing......

Is the B.C.M and immobiliser apart of the on board computer system or are they two totally different compenants all together?

CAS, Battery and Ignition Key Issues

"I was driving my VR and it just stopped."

Primary cause (assuming there is adequate Fuel in the Tank) is the Crank Angle Sensor CAS). This is located on the front of the Engine. People pour water over them to cool them down if the Engine just stops. If the Engine then starts easily you have found the Fault. Replace the Crank Angle Sensor.

"When I tried to turn it over the only noise was the engine engaging but would not crank over."

You mean you hear the Starter Engage but the Engine does not rotate.

You may also have a failed Battery and/or Charging system. Cars with Digital ECU's (like yours) will not start unless the Battery is sufficiently large and in good condition. The Battery must provide a minimum Voltage to keep the ECU working properly under Cranking.

There are 2 issues here:

1. Is the Alternator charging.
2. Is the Battery holding Charge.

I recommend fitting a Voltmeter to your Car or learning to read the one you have. It should read 14 volts anytime the Engine is running.

Also, the Ignition Key Battery will cause starting problems if it needs replacing.

"Prior to it stopping when i would turn the key the engine would engage but then a pause before turning over and starting."

Is this a V8 or V6? It sounds like excessive advance.

"
could it be the timing chain slipped or come off
"

The Engine wouldn't run at all. It can't put itself back on if it falls off.

Ignition Coil Packs fail on these too. Try the easy things first (water and CS trick).

vr v6 wont start after driving wont even crank.

94 vr v6 driving fine to work parked it went back out several hours later and it wouldnt start,played around with the fuses under the bonnet and it went only for a short time,the motor wont even crank and when the lights are turned on they dont work and it makes a buzzing noise from the relay under the bonnet and also the headlight switch.turn the key on and the fuel gauge dont work and central locking dont work eaither,when i pull the hbeam switch the engine light comes on aswell with that buzzing nosie.

VR commodore wont fire up

Driving thru crazy weather yesterday and i noticed my battery light come on! Got home turned it off! went to the shop later and the battery light and engine lights come on! Seemed a bit sluggish! Today same problems, but now i tried to start it, when i turn the ignition on all the lights come on but when i try start it, it wont fire up :-( PLEASE HELP ME! Battery or alternator? Clueless female :-(

Battery Light

I suspect this means the Alternator has failed. If this is the case the Battery Voltage will be low which would be the first thing I'd check by putting a Voltmeter across the Battery or reading the one on the Dash if it has one.

I'm not sure what State of Australia you live in, but NRMA, RACQ, RACV people would be able to tell you the answer to that right away.

If the Alternator fails the Battery will not be getting Charged.

Cranking the Engine will tell you the state of the Battery (slow Cranking means the Battery needs recharging).

Your Alternator Has Failed

Your Battery is flat because the Alternator has failed.

First you'll need to replace the Alternator, then get a jump start from someone.

Alternator!

Thanks so much for your advice, a new alternator will be purchased tomorrow :-) along with the leaking radiator haha, thanks again! :-)

alternator

vr's can be easy and cheap compared to later models - give the alternator a bit of a tap when running, or wiggle the voltage regulator on the back of the alternaotr (the black thing with the injector type plug) and see if the battery light goes out. you will likely hear the engine load up and a slight whistle from the alternator if it starts to charge.

if this happens then all you need to do is replace the regulator (approx $60) or solder a new set of brushes into your existing regulator - very common and way cheaper than a new or reco alternator.

Alternator

Thanks for your advice im now thinking it is the alternator! Ill try get a brand new one tomorrow and replace it! Thanks again! :-)

PLEASE help me get to drive my styley purpled-up xmas pressy :(

VR Problems

"they say it just seized"

Do they mean the Car could not be moved or the Engine seized?

"car is not turning over and nothing is happening."

That sounds like the Neutral Safety Switch which is not seeing Park or Neutral correctly.

"wonder wether they towed it thinking it was in neutrel wen infact the line was slipped into drive or gear????"

Automatics should be towed by the Rear since the Rear Bearing is not lubricated adequately when the Engine is stopped.

"do not want to put this other engine in if i dont need to"

I don't see the need for an Engine change. What you describe is a Gearbox problem so far.

It sounds like you need a competent Automatic person to review the Gearbox and quote you to replace or repair the one you have.

It's risky not having the Selector Indicator working. You need to avoid the possibility of someone selecting reverse by mistake. Autos are very good at engaging Reverse at speed if you ask them to.

The most prestigious Automatic damage is selecting Park while the Vehicle is moving. That will wreck the Park Pawl and Ratchet in an instant and leave the Tailshaft jammed up. That covers your seized description.

Rebuilding the area can be reasonably priced though. Make sure the Governor Hub hasn't become cracked.

You can briefly tow an Automatic in any Gear except Park. Once the Engine is stopped the Gear Selector is useless, except for being able to select Park which is only intended to be used with the Vehicle stopped.

VR no start

Sounds like a bolt has come out of the torque converter and jammed the flywheel. Stick a big socket and bar on the front pulley bolt and see if you can wind the engine backwards.
You will also need to get under the car (don't forget axel stands) and pull the flywheel cover off to un jam the bolt and fit a new one.

vr no crank

remove the serpentine belt and try and crank it over then. i have seen where seized alternators will not allow the engine to crank because there is so much belt grip available with those wide 6 rib belts.

if it cranks then, you will need to check all the accessories and idler pulleys ie alternator, air con, water pump etc..

I have a VS Commodore that won't start until you engage the central locking via the button on the key, then unlock it the same way - then it will start.
