No problem. What all have you tried?
Lets see, I have changed the crankshaft sensor, the camshaft sensor. I have chaked the grounds at the pcm and the block. I have changed the pcm from my other car.I have checked for battery voltage at the pcm, I checked voltage at the ignition feed. I have checked for voltage at the injectors and coils. I have checked rail pressure [56psi] I put on a code reader, no MIL showing. There is more but that is all I recall right now. Jim
First thing to verify is that the VATS is disabled in the PCM. All other stuff is really moot until this is verified.
Check for a complete ground circuit from black wires in PCM connection, probe black wires at PCM connections to the engine block. Black grounding lugs for PCM ground should connect to the rear of the driver side head.
12V constant power at PCM connection on larger gauge red wires.
12V power on only when switched on in the PCM connectors, orange wires.
Continuity through PCM end to sensor end of wires going to crank and cam sensors.
Battery should be grounded directly to the engine block.
I'll add more if I think of it. These basic things should give you fire unless your timing chain is broken or someone put an LS2/LS7 cam in your engine (no pulse generator manufactured on the cam blank).
The fuel pump does'nt run during cranking. That means crank sensor or crank sensor curcuit. Right? Jim
The fuel pump should run for about 2 seconds when you turn the ignition on. It should be triggered by the PCM. The FP will be powered off if it does not recieve a valid VATS signal or crank signal.
PM or post your email address and I'll send you a Holden manual that might help you debug your issue.
