EvilRufusKay Posted December 14, 2003 Share Posted December 14, 2003 Alright Guys, Not a Z but my Bronco that I bought about two weeks ago, I was fixing a leaky heater hose when I noticed the coil was loose just sitting on top of the block next to the distributor. So when I picked it up one of the two wires that plug into the coil snapped. Not thinking much of it I spliced it and started the beast to bleed the cooling system. The truck was running rough, but I ran it long enough to get the air out of the cooling system. So I cleaned up and went to leave. It just turned over would not start. Did some checks, power to the coil with the key in the run position but no spark when cranked. When I started looking around I found a lot of in fact all of the wires in the front harness connected to the distributor were hard, cracked, and had the core exposed. They were all taped up so the previous owner obviously did some rigging. Today I went and got a front harness from a salvage yard and picked up a new coil just to be safe. I spliced in the new harness, mounted and installed the new coil. The truck started right up and ran great...for about five minutes then it just quit. I thought..fuseable link. There was none one the old harness but there was on the new one so I checked it..it was ok. Now I had the same symptoms... 12 volts to the coil but when I crank it voltage actually goes down to about 8 volts. Any ideas guys... I am at a loss.

EvilRufusKay Posted December 14, 2003 Author Share Posted December 14, 2003 C'mon guys...anyone got any ideas? I know some of you are elctrical gurus!!! Thanks, Rufus Quote Link to comment Share on other sites More sharing options...
datsunlover Posted December 14, 2003 Share Posted December 14, 2003 It cranks over fine but just doesnt fire? Might be possible that the coil you pulled from the wreckers is toast.... or maybe another wire somewhere is cracked/pulled off? Hmmm.. could be a bad module.. I've heard of lots of Fords having similar problems and it's because of the ignition module going bad.. its usually mounted on the fender well or the fire wall. Its a little aluminum box about 4" square with fins on it (for heat sinking I guess) and a small harness coming out of it.. That's about the extent of my knowlege on this.. but I'll ask a friend of mine what he thinks. He's pretty good at diagnosing stuf like this.

EvilRufusKay Posted December 14, 2003 Author Share Posted December 14, 2003 Thanks man!! I got the coil from the local parts store so I'm pretty sure its not that. My next step was going to be a moduale so its nice to get a similar opinion as my own. I appreciate the reply. Rufus Quote Link to comment Share on other sites More sharing options...
