1990 YJ 258 6. I have a problem to solve with spark. I actually want to rewire my Jeep soup to nuts. Either that or check each wire and hunt down the culprit that way. Any pointers or advice on where I should start? Also, where can I find a simple or not too tough to understand wiring diagram so I can do this?

No diagram needed really. Start with the plugs and work back from there. Or..... Think back to your lsst tune up. If you can't remember it, get new plugs wires cap and rotor. Chances are problem solved.

I got a factory wiring schematic book for my 87 YJ (11x17 pages, i think about 65 double sided) that shows every wire in detail off of ebay. They are reproductions and I think it cost me about 35 but well worth it, they haynes and chiltons wiring diagrams are worthless. If the PO on your did to your wiring what my po did good luck, not to complicated just time consuming.
