Customer Question

My husband has 2000 1500 Silverado truck. He had the fuel pump replaced because it started killing in idle. The problem is worse now. He has to drive with two feet to keep it running. I heard somewhere there was a reset that might need to be reset

Do you have a fuel pressure gauge? Where did he get fuel pump?

Customer: replied 1 year ago.
No to the gauge. Oreilly's auto parts and a shop near by changed it. Does this mean anything to you. Oxygen sensor circuit high voltage bank 1 sensor 2 I believe this was something a Rileys gave my husband after they tested his oil pump which was reading low

Did they test his fuel pump or his oil pump? Do you know what brand pump he got at O'Reillys?

The bank 1 sensor 2 high fault could be his problem. I would start by replacing the fuel pressure regulator on the fuel rail.

It is possible the regulator may fix his problem.

Customer: replied 1 year ago.
I'm sure it was the fuel pump they texted. The pump I'm not sure of. It reads pfp a0036 f/p assembly and a fuel filter
Expert:  Tool Hut replied 1 year ago.

That is a precision brand. I would still start with a regulator. They are inexpensive and a regular failure part. pretty easy to change with a pair of snap ring pliers.

If the regulator does not fix I would have fuel pressure tested again. If it is under 55PSI I would replace it with an ACDelco pump.
