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.
Thanks,
Rufus
