Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Sounds like a fuel pump failure about to be terminal.
Commodore fuel pumps are the most common failure.
Has the car been checked for codes yet?
Has a Holden tech looked at it?
I would check the fuel pressure to eliminate it as a possible cause.
I've done this with a gauge taped to the windscreen many times.
Was the tank checked for any foreign material prior to the pump replacement?
I have seen the pump connector with burnt out the female terminals.
Once I have proved all of this I would then look at some engine PCM data via TECH2.
Yes I understand you have an LS1 5.7.
That's all good info so far.
The connector for the pump is on top of the pump MRA assembly.
Tank out job, no matter what body style.
Yours is easy, like a sedan.
No worries Lynden.
Come back when you are ready.
Good night for now.
