Anyone know what the signal wire is to the pcm that makes it purge the pump?
Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
have a look at your vx ssAnyone know what the signal wire is to the pcm that makes it purge the pump?
research a pinout diagram thenThat doesn’t help if I don’t know which wore I’m looking for … that’s the question I’m asking now is what wire sends signal to the pcm to start the fuel and I’ll test it
yeah have to agree with yaYou need to provide more info if you want decent advice. What codes do you have? This will guide us to help you.
If it is cranking and you have ignition or fuel it is most likely because the PCM is sending a no start signal to the BCM. This could be cause of a security issue, a comms issue or a sensor issue. See what the car is telling you, look up the diagnositcs and work through it methodically. Jumping all over the place is simply trying to guess when there are so many different potential causes.
Have you downloaded the manual?
Do you have access to a scanner?
What are the codes - current and hisotrical - this will tell the story that allows you to understand the problem.
Once you know the story you can solve the problem - until you do it is anyone's guess.

I will look for you time permittingYeah no worries I’ll try get a mate to scan it as I can’t scan it and the pin bridge on 5&6 on obd doesn’t work… so it is a guessing game until I get it scanned.
Is there any link to the workshop manual or wiring schematic associated with the bcm and pcm etc ??
Can anyone tell me what wires are the ones that tell the pcm/ecu to fire the pump from the key???
