Just finished my 3" lift. Did the front yesterday, started it up drove around a little and parked it. Today did the back. Had to do some heating and cutting at the d/s front leaf bolt. Got everything all done and tightened up and went to start it up and back it out of the garage and it just cranked and crank and cranked.
Noticed under the back seat d/s carpet I melted a small bundle of 3 wires. Black blue and green. I cut out the now bridle and melted together section and replaced the 3 wires. Still nothing just cranks.
The fuel pump isn't kicking on and the fuel rail has no pressure.
Pulled a plug and put it close to a bolt and no spark.
I figured those 3 wires had something to do with the fuel pump but even after its fixed still nothing.
Checked fuses in side and under hood. All good. Switched some relays around still nothing.
Would love to get it up and running and show her off but she won't go.
Any input is greatly appreciated.

The wires you replaced go to the fuel pump and something else (Can't remember what). The "Engine Control" fuse should be blown, and that controls almost everything on the engine.

I do have an engine control fuse blown. 30a I think and it's a big one. I replaced it with the rear door window heater 40a and it wouldn't even crank. When I put the blown one back in it will crank but no go.
