'88 Jeep Cherokee 4.0 6cyl 2WD automatic- Seems like there's no power going to the electric fuel pump. I replaced the fuel pump but I'm having a difficult time locating any of the electrical lines or fuses that link the fuel pump to the battery.

there is no external fuel filter on your jeep, in 1997 they changed the design and put a filter sock over the fuel pump intake in the fuel tank. they only get changed when you end up replacing the fuel pump
Sounds like weak fuel pressure. Need to hook up a fuel gauge to verify. Weak fuel pump or dirty filter or restricted fuel lines. Also possible fuel pressure regulator.
there isnt one. if the fuel pump does not run, ck the ASD and FUEL PUMP RELAYS. Turn the key on and listen real close to the fuel tank, see if you can hear it come on the 2 seconds, Sometimes you can rap on the tank with a mallet or board when cranking, and this will knock it loose, it that gets it running you will need to replace the fuel pump.
the fuel sending unit in the tank needs replacement. check your fuses and relays. this problems sounds electrical not manual. and finally check your fuel pump. this vechile is prone to fuel issues.
Will it try to start if you spray some carb cleaner in the throttle body? If so you need to check fuel pressure and if low, power to the fuel pump while cranking, the gauge not working could be a seperate issue. Could it be that the car is out of gas since the gauge doesn't work? Just asking. If so you may just need a sending unit. If you end up needing a fuel pump, you'll get a sender with it. I've never seen a sender and a pump go out at the exact same time, the use two different circuit's. The ECM really doesn't have any thing to do with the fuel gauge on this car.
