SOURCE: no power to fuel pump.
Have you checked both the power in and power out of the relay?I know the relay clicks but it doesnt mean its releasing power to the pump wire.Have you checked that the earth for that circuit is ok and that the wire to the pump is undamaged?

Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe

There is not fuse for pump but a relay in the relay block. I do suggest jumping to see if pump turns on. Test voltage from ECM if needed. If voltage is to pump, then pump is shot. If not voltage, relay may be bad

The panel or the housing normally lists the names of the items that are controlled by the fuses. If that doesnt work, disconnect the battery terminals and you are good to go

you may need a new computer module. you can check for shorts by identifying where the computer module is and following the wires to your fuse box. this may take some time to do. also check your fuse box and make sure it is in good condition and has a cover, no rust, etc. best bet is to get a chilton's repair manual for your vehicle at a local autoparts store. about 28 bucks. especially if you need to do this on your own. this will help give you the correct procedures for identifying and fixing things.
