I've got good voltage to it and a good ground as well. The spark seems really weak. The car is super easy to flood and once it is it wont start until I unhook the pump and crank it for about 3-4 minutes and let it burn up the excess fuel. I was wondering if these units can partially go out or if they are more of a good/bad type part? I just replaced the crankshaft position sensor and that didn't help. Also, the plugs, wires, cap and rotor are all new.

What's weird about it is that if I crank it for a few seconds without it starting and then immediately crank it again it will start up in a second just like any other car.This is something that the truck has done since the day I bought it.(About 4 months ago) The new problem is entirely different in that it wont start up at all until all the excess fuel is burned off. At this point I think there are only two routes left for me. Sell it/trade it and get a newer, non-renix XJ or completely replace the engine harness and maybe a couple more parts. Some moron had it at some point in it's life and decided to hack up the harness for no good reason.
