Hello everyone again, I'm back with troubles with the black cat Impala. The car stalled and would not restart the other night at the gas station so I left it there and returned the next morning and it started and ran fine. I decided that going back with my car trailer and loading it would be the best, started, loaded and unloaded at home and let it run and after about five minutes it died. checked the fuel pressure and it was 0 psi. After 15 years I figured it was the fuel pump which I replaced with a Spectra Premium and also replaced the fuel regulator for good measure. It did not have fuel in the vacuum port but I've read the regulators on these vehicles can cause problems. After all was done, the fuel pump makes noise but no fuel is making to the fuel rail. The fuel filter was changed about 5k ago and the old pump sock was clean and no debris in the tank. My OBD2 shows P0001 fuel volume regulator control circuit open. I cannot find any info on this. I also changed the fuel pump relay with a working one from my 02 and got the same results. Is it possible that I bought a bad new fuel pump?? Any help would sure be appreciated.
