Engine Electrical issues
Ok, Where to begin. I picked this 85 Fullsize bronco up for 400 bucks. Runs and drives, interior in decent shape, and everything is original. Here recently it has been dying quite literally between 13 and 15 min of being started. It will not stay running. Now after about 20-30 minutes of sitting it will start again, however will die within the 13-15 min. I have replace most of the ignition components I.E Ignition module, the coil andsome of the fuseable links that looked "iffy". Now the weird thing is after it dies, I check all the wiring from the ignition module, the distributor, and the ignition and the coil is getting power yet it is not putting spark to the cap. I have tried numerous coils, wires and Have even tried bypassing the ignition by running a hot lead to the coil. anyway if anyone can give me any suggestions or if you have had this problem please help. Im racking my brain here. Oh by the way it has the carburated 302 with the auto tranny, all stock. [sm=feedback.gif]

RE: Engine Electrical issues
Sounds like a die'n module, but being a replacement already,, have you changed the distributor pick up as well? The older dura spark systems would follow that same fail,stall/cool pattern and the pickup was usually the culprit, or occasionaly the module, and the engine would stall with arestart once cooled a bit.. The TFI units usually would heatand fail the module with the same symtoms, but on occasion will fail the pickup..
