Jan 7, 1. Members Ride: VZ Acclaim. If I do not restart the car for 3 or 4 hours then I have to bypass the relay again. I would appreciate any suggestions or experience regards this problem that I have. Thanks OlderVZDude. OlderVZDudeJan 7, Jan 7, 2. Jan 8, 3. The ECM appears to not be supplying an earth for the starter relay. Still looking for the answer.

Regards OlderVZDude.

I am interested in what the key start connects to within the ECM as this must activate something perhaps even supply the earth to the starter relay coil via leg Jan 8, 6.Log in or Sign up.

The other day my VS just died and would not start again which was only running for 10 mins at the time. Anyway I thought it was the CAS as I poured water on the CAS and it then eventually started and I drove the car back home Today while checking things I disconnected the CAS and was shocked to find that the car would still start and it ran few for a few minutes and then died, so I connected the CAS again and now it will not start at all.

I am not sure the CAS is the issue as it started without it connected, I hope it been disconnected did not cause other problem? The pump seems to be working and I have swapped over the DFI. Code 48 was caused by me disconnecting the CAS.

I am stumped right bow So can any of you guys give me any idea on where to look or should just let an auto electrician charge big dollars to fix it? Last edited: Jan 21, James39Jan 21, Jan 21, 2. Jan 21, 3. Reset it now and let us know.

LS1 JamesJan 21, Jan 21, 4. I have reset the ECU and it does nothing. I have noticed though if you leave for awhile it kicks for spilt second then keeps on cranking. Still find it strange that it had started without the CAS been connected. Jan 21, 5. Do an error check then go from there. Jan 21, 6.

2000 Holden Commodore The car turns over but won't start

It really shouldn't run without the Crankshaft angle sensor. Jan 21, 7. Jan 21, 8. Would a faulty CAM angle sensor stop it from starting?

Jan 22, 9. When I first got my VSV6 it had no cam angle sensor pickup magnet in the camshaft sprocket ,so it was logging code 48, no cam angle sensor signal.

vs v8 commodore turns over but wont start

This didnt didnt effect the actual starting of the car, but it did effect the idle, it used to stall a lot at idle, and would also idle heaps erratically. I fitted a new camshaft pickup sensor magnet and problem fixed, idles perfectly now, so I highly doubt it would stop the car from starting. About the crank angle sensor, I was just reading through the workshop manuals about CAS problems,and it says that when code 46 is set and active, the car will not run. So the car shouldnt start with the CAS disconnected.

Any problems with the CAS signal, that cant be traced back to being caused by a faulty CAS, faulty CAS wiring etc, it says to check the DFI modules wiring and connectors etc, and if no problems found there, it could then be a faulty DFI module thats causing the problem.

VT Commodore won't start The car was running fine the night before when parked. Next day the key is turned and the engine turns over and it tries to fire and tries to start but won't. I had an issue a couple of years ago where it seems the body controller got in a knot and the cure was remove battery power to reset it. I did this but made no difference. I checked the computer codes and all is ok but I may of cleared any codes from the computer when I disconnected the battery!

I pulled each spark plug lead off one by one and put a screw driver up and held close to earth and spark from all 6 leads. I puttled a couple of plugs out and they are wet so there is fuel.

Also you hear the pump pressurise the fuel. So now I'm at that point where I'm not sure where to look. For a while it was taking 2 cranks to start but I was just putting this down to age. Any advice on what to check next? Should of bought that new XR6 last year lol Leroy. God help you if you have lost the radio code as well. You have spark, you have fuel, you should have a running engine Sure its not flooded? Wet plugs means wet cylinders which means its difficult to crank due to the compression and fowled plugs.

So you have spark, and fuel, do your injectors pulse on time and does your spark come on time CAS crank angle sensor OK? The CAS is behind the harmonic balancer, it controls the timing of the spark and injector pulse. Just double check your spark and injector pulse first Leroy before attempting to fix itLog in or Sign up.

Jan 3, 1. I was driving along the other day and my car just stopped on me and wouldn't re start, I noticed fuel pump not priming which was odd as I have only put a new one in bout 2 months ago, anyhow I put another one in and still the same problem, checked wiring fuses relays ect all good?

There are also no codes coming up, thought maybe something to do with immobiliser as I have heard that can stop your fuel pump priming on ignition. My key still locks and unlocks car with security light doing the norm so could it be the bcm itself? If anyone can help or suggest anything that would be great. Vs v6 auto sedan. SonzcomJan 3, Shawen likes this. Jan 3, 2. Hi if the starter is cranking then its not immobilizer WozzaJan 3, Jan 3, 3.

Jan 3, 4. If you have run it dry a bit, then you may have killed the new pump? Jan 4, 5.Does sound like your alternator. Very similar happened to my falcon, then again but it was because my alternator wasnt producing power to the battery.

I'm sure ill be corrected by some wanker on this site, Good luck with it though. QUOTE hiluxpigga Oct 13PM Hey i have a VS commodore that i picked up off a mate that was running and had been sitting around for a few months put it on a trailer and took it back to mine put fuel and a charged battery in it all the lights on the dash come on but just a dud click is all its making its not turning over and it doesnt really sound like the starter motor clicking but it could be can anyone give me some advice or ideas on what it might be sounds like solenoid has gone on starter motor.

I'd be inclined to say starter motor, if its manual give it a push start? Don't know allot about ecotec engines but that's where I'd start. Starter, Battery, Battery leads, Earths, etc etc Start there and see how you go, does it turn over by hand?????

Recent Posts Contact Us. Just Commodores. VS V6 auto sedan, cranks but won't start. May 16, 1. I've got an intermittent start problem, engine cranks but won't fire. It first happened a couple of weeks ago, then it's been fine until last week. My wife was in town, car wouldn't go, she rang the RACT, the bloke had a look, banged the tank, the car started and he said to get a new fuel pump. It happened again yesterday, I was in the car this time, leaving a set of traffic lights it just died, banged tank etc.

I walked home, but before I got home my wife rang saying the car was going again and she picked me up. We jumped into my car, I ran her in to town, came home and replaced the fuel pump. I dismantled the old one and couldn't find any reason why it wouldn't work.

vs v8 commodore turns over but wont start

Went to start the car this morning, same problem, fuel pump was running, cranking but no start, the fan was running, then stopped, I turned the key and the engine started.

Each time it does it the radiator fan starts running air con offeven if the engine is cold. I've done some reading through the forum and it appears that this is not an uncommon problem, but haven't found a solution yet. I've read the section on error codes, checked it this afternoon, but all I get back is 12, system OK, no faults logged. I'm at a loss as to where to go from here. I haven't checked to see if there is spark when the problem arises, but that still wouldn't fix the problem.

Any suggestions appreciated. Cheers, Mick. MickMay 16, May 16, 2. It can cause similar problems to what you have described. May 17, 3. Yeah probaby CAS.

V6 Engine will not crank over but will start if I bypass the starter relay.

Same thing happened to me. Check for injector pulse multimeter and spark when the problem occurs. May 17, 4. Thanks for the responses, my wife rang me this morning saying it had done it again, cranking, no firing, radiator fan on. I told her to leave the ignition on for a while, after about a minute the fan turned off, I told her to try starting the car and it went. Is it worth fitting a second hand CAS or should I bight the bullet and buy a new one?

I've already replaced a fuel pump that didn't need it so I'm hesitant to fault find by replacement, it can get a bit expensive. Is there any way I can test the CAS or prove that it's the problem?

Just Commodores. VT kicks over just wont start!! Aug 19, 1. I saw a few threads sayin give the starter motor a knock with a hammer, or turn my key right to the point before ignition leaving for abit then trying to start, but nothing seems to be working. Aug 19, 2. There could be no spark. Check for spark. If there is spark the ignition side of things are good.

They talk to each other upon start up. The PCM enables the fuel system. Or even the PCM could be playing up.

Turn the radio off so you can here it. I had a read through the owners manual, and it said to turn key to ON position ad leave for 2 hours turning all accesories off. Hi there so is your led turning off when you try to start itand i take it your lcd screen isnt switch from klms to instants etcmmmmm sounds interesting ,just guessing maybe your key barrel is worn, bcm is nackered.

Have you bridge the diag connector to see if any codes have been spat out.

Also could be a bad ground check you ground wires from battery to body and batter to engine block. Is your starter motor turning motor over just not firing or nothing. Aug 22, Cheers and thanks to Braddz93 to start the topic.
