Fuel pump seems to have gone out on my 2000grand cherokee larado trying to check pump fuse but don't know which one it is, because fuse box cover is missing

2WD or 4WD...V6 or V8

check wiring diagram for the 1995 Jeep Grand Cherokee radio?

I would check the fuses in the fuse box first there might be a fuse for the fuel pump that's burnt out.As far as the relays it should say on the inside of the cover to the engine compartment fuse box.If you have the owners manual it should say in there also.

Most likely the ignition coil assembly, in some cases the ignition module is faulty.

Its in the gas tank

Check the fuel pump relay which is under the hood behind the battery. You'll see 2 turn clips to remove the cover. It should be the 2nd relay as your looking at the car.

Was it empty when you parked it? (i.e. did someone drain the tank, and put sugar in it? something like that?) If not... the fuel filter could be clogged. Check that. Most cars of this age are fuel injected, so the fuel at the fuel filter will be under high pressure. Chiltons manuals usually discuss how to de-pressurize the line if needed. But you probably already dealt with this changing the fuel pump. Good to hear it's turning over. After (finding) the filter... check to see if any fuel is making it through the filter. Turn the ignition to "on" and it will likely start the fuel pump and spray fuel everywhere (if you disconnect the filter output.).... besides having a mess, you will know your fuel pump works. (Try attaching a hose from the fuel filter output to a bucket to prevent a mess and possible fire please ). Can you hear the fuel pump running? Could be a blown fuse for the fuel pump.

if over 100,000 miles miles common.

I don't remember seeing any fuses for that on the one I have...It's dark out now and I don't have a light that is working out there. I;ll look tomorrow but like I said, don't remember seeing one, and I've been through that system hundreds of times. Only two palces it would be is in the power dis center near the battery or in the under-dash block. If the relay failed before, it was likely because the pump draw was too high, so youre on the right track.

turn on the car and listen outside under the car.... are you able to hear the fuel pump ?
and there is a shut off ... for fords it's located in the rear compartment cover area where the jack is stored.
