Fuel pump on/off
I searched for an hour trying to find a similar problem/fix. Its a 2000 Malibu. Just replaced my fuel pump 2 days ago thinking all problems pointed to fuel pump. Was losing power especially up hill and would turn over and over before starting like it lost its prime or pressure. Yesterday I tried turning it over and the pump wasn't coming on everytime I turned the key to power the pump. I did this more than a dozen times with the Bu starting 50% of the time. When I heard the pump come on it would start first turn. Had fuel pressure checked at rail(43psi) new filter and pump replaced with a used one from an 2001. Where do I go next?
