i just replaced the faulty fuel pump on my 92 buick regal. But the car still will not start. i think that i did everything right. how much fuel should you put back in after changing the pump?

What brand pump did you put in?Most aftermarket pumps are junk.Delphi pumps from the dealer or your nearest Carquest parts store are the way to go and last longer.General rule is not below a quarter tank.Check your connections also.

what is your fuel pressure reading now with the new pump?
