Did the car start before you installed the new pump?
Did you have fuel pressure?
Do you have poser to the fuel pump?
Do you have a good ground at the fuel pump?
what engine do you have?
Why did you replace the fuel pump?
Pam, was the fuel filter replaced at the same time that the fuel pump was replaced? If not, replace the fuel filter. Often, the filter will get clogged with debris. When that happens, the fuel pump will be ruined. Replacing the pump without replacing the fuel filter can ruin the new pump. It is also possible that your new fuel pump is defective. Now that most replacement parts are made in China and the third world, there is virtually NO quality control. I'm a professional mechanic and defective brand new parts are a BIG problem in this industry. Was the fuel pump relay replaced when the new fuel pump was installed? Always install a new relay, as a failing [your old] fuel pump will often damage the relay. This will cause problems with the new fuel pump. I would advise that you install a fuel pressure test gauge to the engine. This will allow you verify whether or not the engine is receiving enough fuel pressure. If the pump works but the pressure is low, also check the fuel pressure regulator. The web links below should help you.
If the fuel pump(s) run while the pressure is falling, replace the fuel pressure regulator and (although I'm sure you've already done this), replace the fuel filter. If the fuel pumps appear to be turning off by themselves, replace the inertia (fuel cutoff) switch.
Do you know for sure that the fuel pump failed or do you have a bad relay? If the fuel pump relay is good no you don't need to replace it. The fuel pump unit comes with the sending unit and a sock filter. I would replace the inline fuel filter when you replace the pump. In line fuel filters need to be replaced every 36000 miles. If that filter starts to plug up it makes the pump work harder which leads to premature failure.
no. the noise you're not hearing is the fuel pump. When u turn ur key on you should hear a buzzing like sound from the rear of the vehicle. If not, and ur car don' start, probably fuel pump. Just to verify the faulty fuel pump, have an assistant open the fuel tank cover and remove the gas cap itself. With you inside turn just the key on, and have your assistant listen for the "buzzing" or "hummin" sound. if nothing there, then faulty fuel pump. If noise is present, then perhaps you have a different problem like nothing is reaching the engine, fuel wise. Like a plugged fuel filter. when replacing the fuel pump, ALWAYS do the new strainer as installing the old one could cause a whole new set of problems and eventually wipe out the new one as well *RULE OF THUMB, WITH NEW FUEL PUMP, REPLACE FUEL FITLER.* this will be easier on the pump output to the engine. good luck.!
