The root of this thread started 3-4 years ago but I will try to just touch on the main points, long story short, A few years back I had to do a 4.0 head swap because my head was cracked, but at that same time (before I got the Jeep running again) I did the nutter by-pass and it has never started since then. I followed the by-pass instructions to the letter. I twisted the spliced in wires, and I reused the same purple and orange wires to the distributor.
Due to a massive amount of other problems in my life (as well as the number of things that need to still be fixed on the Jeep) I didn't work on it much except a couple times a year since I didn't really have the funds to get it back to 100%. The times I tried I couldn't get it to run and was endlessly frustrated because everyone I knew had tried everything they could think of. Then finally some one figured out it wasn't getting spark (well, it was but it wasn't more on that in a sec)
Earlier this year I started to get more opportunities to work on it (lack of funds kept me out of school last semster) and after replacing the coil, cap/rotor, plugs, and wires I finally got the problem traced to not getting spark except when the ignition was released from start/crank to run. So I looked around and found that the problem was likely the ICM.
So a 2 weeks ago I replaced it, and we decided to just try it without the nutter bypass and it had spark enough to backfire all kinds depending on where the dist. was rotated!!!("friends" previous attempts to "fix" the timing left it severely out of time). But, I finally had proof of spark! Well, I was running out of day light and decided that I would set up the nutter by-pass and then the next time I could work on it (I am back in school full time, and due to medical problems generally need help to work on it much).
So tonight, when my buddy could help again, I figured set up the timing and it should fire right up!!
I was wrong
after finding TDC in cylinder #1 on the compression stroke we go to crank it over and nothing not even a pop. I make sure my carb is primed (last time we had to crank for a while and pump the gas pedal to get it fuel) but there was gas spraying in the carb so that wasn't the problem! So we go to test for spark and nothing until I release the key from start/crank to run! So I am wondering could the nutter by-pass be the cause of ALL MY PROBLEMS!?!?!?!?
So I reconnected the ICM wires and still no spark!
I dug around as much as I can on here and the only likely possibility that presented itself is that someone said,"How did you join your wires? Crimp connectors, solder, twisted?
It needs to be a good connection. You can't afford ANY voltage drop on these connections as the signal is only about 1 volt AC."
That was taken from post #5 here
I used crimp on blade connectors so could that be the problem? I am more than interested in replacing them, but what should I use instead?
Also, the fuel in the gas tank is 3-4 years old and doesn't really smell right should it be drained? We tried to siphon it, but couldn't get a hose down the gas filler neck. We tried 2 different hoses, but neither fit. If it needs to be emptied what is the best way to drain it?
After years of having to look a my Jeep sit dead on the side of the house, and I finally have a means (financially and physical labor) to get the Jeep back up and going again, with the fixes it needs, but I need it to run otherwise, well it isn't running and is still useless.
PLEASE HELP ME FIX MY JEEP!!!!
