cranks over but no start.....need help!

[TrevR32GTS-T]

Need help! I was driving and the car shut off. All lights are on and crank and cams are moving. I have changed the crank sensor and ignition amp. I can not hear the fuel pump run but it is getting fuel. I have ohm check the coil packs and are good. I have not check the ecu code yet. Can anyone help? Thanks, Trev

The cpu is saying all ok on two cpus. Can a AFM cause this problem too?

[predator]

starter motor? But if it cut out while driving sounds more like ignition related ...hmm

[TrevR32GTS-T]

There is no spark. I am puzzled.

[blind_elk]

If no spark, try a new ignitor module (little black box at the rear part of the cam covers).

[TrevR32GTS-T]

I have tryed that. I am going to try AFM today. To make sure it did not get fryed. It was snowing the day it die.

[paulr33]

check all fuses

[ABuSD]

same goes for mine, i got told it could b the crank angle sensor or the igniter module,

Can an Auto Electrician, diagnose what it is for me?

Buying a CAS and/or igniter seems a little bit pricey if it turns out i dont need them!

Cheers

[TrevR32GTS-T]

Was not the CAS of igniter. I tryed coilpacks, coilpack harness, AFM, all the ign relay, shot wires, and fuel pump because, I can not hear it prime the system. I have checked the vac. lines and fuses. Going have it towed to garage that a friend toke his GTS-4 too.

I had a cann car to get parts from to troubleshot mine.

[TrevR32GTS-T]

I mean CAS or Igniter.

[ABuSD]

All the best, plz post up how u go!!

[sweetr33]

lots of stuff changed huh, easier way to check if it was getter fuel would have been disconnect the fuel line goin into the rail and ignition on or crank whichever it needs to get the fuel to come out, SOME systems dont actually prime up on ignition on and require the car to be cranked to get the fuel feed up. Checking coil packs was a little bit of a waste of time cos it will still run if one drops out, just like a dog. But see how u go at the mechanics. Update when u know champ

[TrevR32GTS-T]

I will keep all up to date on what I or the garage finds out.

On another note, the car is getting fuel. Tryed the popping the line of and filled the can quickly. My friend and I found there was 2 volts coming out of the igniter amp (the one on the coilpack cover). I am going (I hope!) another igniter amp today. I do not like giving up. Thanks for support!

The car will start with no AFM attached, so it's not necessary to check at all.

How can you be sure it's getting fuel if you can't hear the fuel pump? When you switch the car to "ON" without starting, you should hear the pump prime. If there is nothing, then the pump isn't pumping. You will have fuel in the lines already even with no fuel pressure, so d/c the line and seeing fuel is no way to tell. Get a friend to stick his head in the boot when you switch the car on, he should definitely hear it prime from there. Even the quietest pump will be audible from there (turn your damned stereo off! )

You've said there is no spark, well that's definitely one cause of it not starting whether or not the fuel pump is working. If it's not the igniter or CAS, then it could be the ECU not telling the igniter to fire. Try checking all wiring connections and maybe swapping ECU's with a known working one.

You may be getting fuel to the other end but if you don't hear it prime the system then the system won't be pressurised.

Maybe the fuel pump dies as soon as it gets a little bit of load on it.

I can hear my 32 pump prime almost every time I flick the key. Wait a minute or so between priming otherwise the pressure will be there and it wont prime because it doesn't have to.

[TrevR32GTS-T]

I do not hear the pump running. I have changed the pump and pump relay. The gas tank is not getting pressured (taking off the gas cap).

[ABuSD]

The gas tank is not getting pressured (taking off the gas cap).

So whats this mean?

Had the auto elec around today on mine but no luck didnt find out what it was, gonna hunt down a CAS & Igniter module.

Trev do u have any interceptors/piggyback comps. hooked up 2 ur computer?

I have an SAFC & ITC these couldnt b causing the problem?

[C_DawG]

Just pull a fuel hose off and see if it sprays when you turn the ignition to 'reds'. My fuel pump still made a noise when it didnt work, had to be replaced.

[TrevR32GTS-T]

My gas cap for my gas tank is not vented. It helps the pump run with less stress. My tank is not get pressured. I do not know if, the pump is crapped out, the car will not start as a safety reason not to run the car too lean and kill the engine. :Bang:

[TrevR32GTS-T]

Fuel is coming of the fuel line but, no audio from the fuel pump. I have alway been able to hear it and get the 5-second prime. My fuel mileage was very good before it stopped running. I had to fill-up once a week. It is quiter than my gt-r pump I had it there. :hellpisd: :cuss:
