Vs V8 not starting

[Jarrid]

Hey all posted a week or so ago and now my problem has escalated, over the last two weeks I've had an issue where the car would sometimes start no problem then other times just turn over. Now it wont start at all no codes, I have pulled the covers off and airbox as ill do a bit of service over the next month plus the clutch needs replacing (which brand clutch is good to go with for a cruiser that is treated well, smoother is better for me?) ill replace filters,spark plugs the rest of the hoses leads what else should be done? does this sound like the immobilizer prohibiting the motor?

If its cranking then the immobilizer is not the issue...try using the search as Ive seen a lot of these types of questions this may help

My VQ did a similar thing ages ago. Would just crank and crank for no reason at all it would seem. Usually after it had been running or it was a hot day. Replaced the temp sender for the ECU and fixed it.

From your description, it sounds like the ignition module has failed. Other possibilities are coil, Hall Effect Sensor (in distibutor), or fuel pump.

Have you given the sensors a spray, maybe the computer cant get a fuel air mixture because the sensors aren't picking up anything, the crc and sensor spray is just mineral alchol and you can put it in a spray bottle and spray it on the sensors soaking the dirt oil pollen crud etc. hope this helps

Does it eventually go or does it just crank and crank?

So its weird because one day it would start first time then the next nothing but now its just stuck cranking and cranking. ill wait till this weekend to try all the possibility's, I have a rebuilt 5lt in the shed so I can swap the coil and ignition module.
bloody hard to find time now there is a little one in the house and Im picking my new daily up.

When the coil died on my 5L it did it slowly. Gradually got slower to start until it would just stop while driving. Then it would just crank for ages and slowly chug to life.

Will probably be coil, ignition module or the hall sensor in the dizzy.

When you bridge out the pins on the diagnostic plug does it flash any codes at you?

Actually on my wife's VR sII 1995 V8 5Lt Calais, a few years back we had an issue with the immobiliser failing in the BCM
and not allowing the pcm to throw a code.
The car was cranking but nothing else. occasionally it would start but if it decided to quit it would not start again.
This was off the road for a couple of months I kept getting from the auto elecy and the mechanics that had come around saying "it's not the hall effect trigger,
they never go it's gotta be the ignition module".
I changed out the BCM and low and behold the PCM threw a code 46 no reference signal while cranking.
I replaced my hall effect sensor in the dizzy and it started first go and didn't miss a beat.
In the couple of months off the road I replaced - ignition leads, Coil, Dizzy cap, Ignition module (twice), engine coolant temperature sensor and Throttle position sensor.
in the end it came down to something the Mechanics and electricians said doesn't happen.
persevere and you will get it eventually.
If you want to eliminate the BCM from the equasion try going to the wreckers and get a BCM of the same level and a key fob to match.
If you buy a new one they are expensive and you need to get a key fob coded to match the bcm and it may not be your problem.

I hope that helps somewhat!
