Re: 1991 camaro fuel pump issues

oh and when was running it would sometime stall if i put it in reverse the engine only has msd wire and performance exhaust do you guys think that stock fuel pump was not getting enuff fuel if so should i put a 255lph pump because its getting a 383 a little down the line or would that be to much fuel in the meantime for the 305 h.o i have now?

Re: 1991 camaro fuel pump issues

Sounds like maybe you didn't have a good ground reference when taking those measurements? You should have ~12V to the pump. If not, I would go back to the fuel pump relay (by the brake booster) and see if it has 12V in and out.
