I've ran into a problem. My 89' 3.9L 4x4 has stopped running. Not getting spark and fuel pump has stopped working.

I've replaced the fuel pump, computer, ASD, coil, distributor and Hall Effect again.

I'm worried they guy who had it before me did some unsavory wiring, he had put in a switch for the fuel pump, which I disconnected. It went from the +side terminal of the battery, directly into the switch and the +side of the coil.

Any one wanna give their .02¢?
