Help Bronco won't start!!!!
Okay I have a 1980 bronco with a 351M and a Duraspark II ignition. The wife was driving it and it died while it was running off the original coil. I took the Omni pak off because it was sparking around the lead wire but it worked fine.
Now I have an after market coil (Jacobs Omni Pak) and the original coil is still installed so this is what I did.
1. Replaced ignition module with another one but won't start;
2. while cranking it over no spark with coil or Omni pak;
3. if I put the key forward to accessory, before it cranks, the Omni pak provides spark;
4. put the key past this point so it cranks the engine and the spark stops.
Any ideas? I'm just lost on this one because I get no spark out of the coil or the Omni pak while the engine is cranking.

i had a very similar problem with my 79 bronco,it would turn over but no spark,I changed every electrical part related i could think of including my wire-ing harness, the only thing i never checked was the distributer and that was the problem all along. So I would say start there.
