What's up guys, I have a 91 YJ that keeps blowing the 30 amp fuse for the fuel system. I'm thinking either a wiring problem or the fuel pump is on it's way out. Any thoughts? Sometimes the fuse blows as soon as I turn the ignition to run, sometimes the jeep will run and drive fine for a few hours before it blows. Any ideas would be greatly appreciated.
Sounds like a short. You might want to trace the wires and see if there are any bare spots or crossed wires. I've seen some issues where people jumped in additional wires to power other devices and the draw was too much.
