VT Wont start Please help!!

[dope505069]

Hi guys I have a VT Olympic edition 2000 model 3.8l auto and today I turned a corner at an intersection and my car went dead or stalled. After that I could not get it started. Would u have any ideas?

Any suggestions would be much appreciated.

I have plenty of fuel in it half a tank.
Battery is fine.
It wants to kick over but just doesn't.
I believe the starter motor is fine its sounds fine.

My guess is maybe a fuel blockage or something.

I dont want to start pulling parts out if i dont know what it is or playing with the fuel system as im not that experienced but any suggestions would be great.

Im gonna go out now and check the fuel pump fuse and listen if the fuel pump is on but other than that im not sure.


Ok j just changed over the relay for the fuel pump no success. Im thinking now maybe its the fuel pump or fuel pressure regulator I did hear the fuel pump buzzing though pretty expensive things to change if im not sure that thats the problem lol.

grap a pole go 2 the fuel tank n smack it wit th pole n try 2 start it again

[dope505069]

Why thankyou for your input ill go try that right now not. Ive read a couple of posts is that ur answer to everything just smash it with a pole lol.

fuel filter blocked is there spark ? or is fuel getting to the motor.. or maybe one of the throttle body sensor or airflow sensor or even could be the computer lol if its no fuel i would first check at the fuel filter how long since u have changed that ?

[dope505069]

I changed the fuel filter around three months ago. There is spark I changed the fuel pump relay with the low beam relay and still didn't work then changed it back no luck im not sure exactly if fuel is getting to the motor but i can here the fuel pump definitely turning on whether it works or not i dont know. How do i check the throttle body sensor or airflow sensor. I pretty much have to change them right another expensive thing to do if thats not the problem lol. Its just my luck. I feel its definitely something to do with the fuel though.

Ive read abit about immobilisers can cause this problem my alarm has had the dick and goes off when it wants to could this be a possible problem? This has never happened to me before.

[Bushy]

well if there is spark normal i think that means the immobilisers is off.. ( im not shore but i though that it turns of the coil from sending spark but im not 100 %)

see if u can remove the fuel line.. if u have the tool to do this or unscrew it from the back of the injector rail.. and if fuel comes out when u turn ignition on u have fuel to the motor.. as its only a push in line with a o ring on the injector rail .. ( or is that only the vs im not shore how it works lol.. i know its different on the VXII not shore about your car)

Thanks mate ill try and see if fuel is getting to the engine that way.

All of the above plus check the plug connection at the coil packs and give it wiggle and a close visual inspection; it could be dirty/loose etc.

[dunky]

Also try locking and unlocking with the remote

[dope505069]

Thanks for all your help guys ill give it a go in the morning.

. How do i check the throttle body sensor or airflow sensor. I pretty much have to change them right another expensive thing to do if thats not the problem lol.

go and talk to a wrecking yard and see if they may lend u the parts to test it as u are not shore.. as there are some nice people that will try to help you.. ( or leave them with some cash so u can get it back when u return the parts )

if not .. i think a scan tool can pick up on them folty sensors in the car.. im not 100% shore but it may be a possibility.. so once again ya phone comes in handy to call some one who has the scan tool to ask them or maybe some one on here may know if it possible...

but the it maybe an immobilizer as im not shore how they work in cars now.. as it may do something in the computer but if it works the same as the stranded commodore one it wont even crank over...

crank angle sensor or fuel pump most likely CAS

[Bushy]

crank angle sensor

i forgot about that one lol

[dope505069]

Ok well I am changing the crank angle sensor tomorrow so yeah I am not sure if that's the problem but worth a try as its only $30 . We listened for the fuel pump again today turns on and we changed fuses and relays i got from a wrecker (tried a couple). I also want to know can the fuel pump still turn on and sound if its stuffed and also what is the chance its the engine fuse the 60 amp would my car even want to turn over if that was gone?

[curtcommy]

CAS. had same issue. gives ya the shits, only happens when its hot/peak hour traffic/ur in a hurry to pick up a lady or running late for work.

[delcowizzid]

dont forget when your in the middle of a tunnel man im getting sick of that LOL

[dope505069]

I see yous are explaining something that happened on and off for you this has only happened once for me and since it has happened the car wont start period.

The main reason I think its the fuel because I actually stalled while driving it actually happened while I was accelerating around the corner and it was in an auto.

After it happened I couldn't start it. Its not that I turned it off and then
couldn't start it.

Also the main things I need to know is,
1. Can the CAS make you stall while driving?
2. Can the fuel pump still turn on and sound if it has gone?.
3. If your getting spark does this mean your CAS is ok because im getting spark?

Thanks guys for all your help and input its been much appreciated.

Hi all , my first post on just commodores . Had the same thing happen to me just 2 days ago .Engine cut out after giving it a boot full 100 m from home , managed to roll and park it in the workshop ..phew . Plugged the scanner in and it came up with intermittent connection to the CAS . to cut the story short it turned out to be the plug connection to the coil pack . Gave it a wiggle and the heap runs fine again . Must have disturbed it when gassing the air/con earlier .

[dope505069]

Thanks I will try that 2.

[dope505069]

Hi guys theres a few things I need to know ,

1. Can the CAS make you stall while driving?
2. Can the fuel pump still turn on and sound if it has gone?.
3. If your getting spark does this mean your CAS is ok because im getting spark

[Brett_jjj]

Yes,the CAS can cause it to stall while driving if its on its way out..Its usually heat, combined a worn out CAS that can cause it,sometimes if you pour water over the CAS,it cools it enough to get going again.It would be unusual for the fuel pump to be running,but not working.Usually when they die,they just completely stop and wont make a sound at all.Although theres still a chance that it can still run,and not have enough pressure to start the engine ,but its rare.Ive never seen it happen.And Ive fixed quite a few of these fuel pumps in my time.And theyve just completely died,no sound at all.

B4 u start changing any parts do a self diagnosis 1st and see if u find any fault codes urself then get back with the results

Checking error codes VT/VX

[dope505069]

Hey i just read the guide awesome thanks for that I just don't know where you are to count the flashes from is it from the trip computer or from that little red fake alarm looking light near the mode button.
