1989 Jeep Cherokee Laredo

I have an 1989 Jeep Cherokee Laredo that I had parked for about three years. I started it occasionally at first but this last year I hadn't started it at all. So far I am not getting any fuel at the fuel rail. I had replaced the fuel pump about eight months before I parked it. I replaced the fuel pump ballast resistor since those tend to go out quite often. When I try starting the Jeep, it cranks and cranks but won't start. The Ballast resistor gets smoking hot, and once the ballast resistor wire on the Starter Relay side burnt. I replace the wire and decided to check the jeep for any electrical shorts. So far I have noticed that under the jeep at the fuel pump electrical connector (pigtail)when disconnected and tested with a test light, the connectors have juice, but once connected and tested at the wires going into the fuel pump there is no juice. Any advice????? Please...

Is it possible for the Fuel Pump to have a short and be causing the power to return to its original source causing some kind of short???

Could be something with the ignition. Maybe bad. Try replacing the cam position sensor.

89 has no cam position sensor.

OP: Inspect the relays on the passenger inner fender and the associated wiring. Any chance some rodents got in there and chewed stuff up?
