Re: Ignition Problem-90 Jeep Wrangler
And -- get those plugs gapped to where they should be. .045 is way too much. Make them .032-.035.
Reason is you haven't done anything to increase the power - voltage, current, burn time, etc. of the ignition system.
Using the bigger cap provides better insulation only, no power increase.
Using the TFI coil with the resistor still in place LOWERS the coil output (it's designed to NOT use the resistor.) BUT you cannot eliminate the resistor to make the coil work better unless you change to a different module, like the GM HEI. Eliminating the resistor with the original module is asking for the module to fry - way too much current.
Since you had it running once, albeit not well, bet it'll start with the plugs gapped right. I'm ASSuming you do have the correct plugs FOR THE ENGINE installed, not for the TFI system.
Bet it's a little flooded from the playing around with it. Try pulling the coil wire off by about a 1/4" gap - that will help clear the plugs. Once it's running good, push it back in.
I'd get it running as it is, then convert to the HEI like the link says. YOU WILL LOVE IT!
Reason I say get it running as it is is in-case you do something wrong in the HEI conversion you aren't fighting multiple problems. One step at a time.
Let us know how it comes out.
