in the power distribution center underhood are you sure it is a fuel problem? they had more problems with the coil and crank sensors make sure you also check fuse 9 in the run position to make sure it is good the fuel pump relay is next to the asd relay

I have replaced the fuel pump, the alternater, starter, spark plugs and spark plug wires, the crank sensor, and the spark plug ignition coil, and the fuel pump wasnt turning on because i couldnt hear it switch on.

Run a fuel pressure test or jumper the contacts of the fuel pump relay and verify there is battery voltage getting to the fuel pump on the Green/Black wire. Verify the Black wire is grounded all the time

DO YOU CHECK FOR POWER AT THE FUEL PUMP AND GROUND? IF NOT DO THAT. THE FUEL PUMP RELAY IS UNDER THE HOOD IN THE POWER DISTRIBUTION BOX NEXT TO THE ASD RELAY. THE LAST COMMENT WAS ON HOW TO DO A FUEL PRESSURE TEST.

the ground is the black and green wire under the hood next to the batter is that correct because its on tight.
Expert:  diagman replied 7 years ago.
THE GROUND WIRE IS THE WIRE THAT COMES DIRECTLY FROM THE NEGATIVE SIDE OF THE BATTERY. WHAT BLACK/GREEN WIRE ARE YOU REFERRING TO? If it is the wire to the fuel pump relay it goes directly to the fuel pump it gets energized by the fuel pump relay. THE LIGHT GREEN/BLACK ARE POWERED UP IN RUN OR START. THE RES/WHITE GOES TO THE TRANSMISSION RELAY. aND THE BROWN/WHITE WIRE SUPPLIES GROUND TO THE RELAY FROM THE COMPUTER
