Fuel Volume regulator/pressure regulator
Discussion
Hi Guys, I'm getting an intermittent check engine. Fault,which on viewing suggests possible fuel pressure regulator issue.
I know when I had fuel pump issues the pressure was going higher than normal then dropping away ( probably due to an internal seal leak in the in tank pump).
The new pump fixed the weak mixture issues,but I still get the occasional 0002 fault code.
Any thoughts,or part number for a new regulator?
It's 2004 large boot Monaro V2 gen 3 LS1.
Thanks in advance.
The car is running fine by the way.
I'm wondering if the regulator diaphragm has gone hard with age?

I have an early 5.7 VXR big boot.
My infrequent engine check light was cured by replacing the O2 sensors. The car ran seemingly fine though and it only occurred at idle. Just a thought.
Otherwise, have you replaced the fuel filter recently. I know the scheduled replacement is very infrequent, but these cars are old now really.

Well,it does seem a coincidence that the fuel pressure when measured went high before it collapsed ( before the pump was replaced and the fuel filter was replaced at the same time.)
The fault code it threw up 0002 on my cheapo reader says fuel pressure/ fuel Volume regulator.
Do we know part numbers for these? Or indeed O2 sensors,which I agree are a very common fault.

You're probably right, probably nothing to do with the O2 sensors. This was just my experience with an intermittent engine check light with an otherwise perfectly running engine.The fault code it threw up 0002 on my cheapo reader says fuel pressure/ fuel Volume regulator.

AAS changed my O2 sensors, with 2 x Bosch 15703.

Now when I did a search, these didn't come up as the right ones for the car, but that is they fitted and my problem was cured
