I replaced the fuel pump relay in fuse box, checked all fuses are ok, I replaced the fuel pump still I hear NO pump priming or running, Could this be the fuel pump resistor? and can I test the power to the pump and the resistor before replacing the resistor? Any help would be most appreciated, I can't afford dealer prices.. Thank you POOR

First, check to see if there is power to the pump. If there is, check for a bad ground. The pumps go out all the time in these cars here is a guide to show you what you are in for when doing the job and diagrams to show you what it will be like for your car.
