No Spark
I had spark on Sunday, but lost it once I fixed the Gas problem and put a new battery in. I have replaced the cap, roder, plugs, coil, had the electronic module checked, the 87 4.9 L cranks over but I can not get any spark to the plugs or even to the top of the distributor from the wire coming from the coil.
What else is there to check or replace to get the spark back?

Ahoy, we're in the same boat
I have the same problem as you. My starter began turning slower and slower over two days, then died completely. I replaced it, put in a fresh battery and enjoyed myself emmensely. It ran great, but then wouldn't turn off. I didn't have time to keep messing with it, so i just but my foot on the brake and stalled it out. The next morning, I ran an errand, the truck was fine, still wouldn't turn off. That afternoon, I have NO SPARK. I checked the voltage at the cool, swapped the coil. Still nothing. I want to know why the spark is gone when nothing has changed. If I get an answer/solution first, I'll let you know. Good luck.

Hmm...let me tell you what I have. I have a stock 1960 F-100 with a 292 V-8. Between the battery and the spark plugs, we have wires, coil, distributor and more wires. No computer to foul things up. Any ideas? anybody?

No spark either
I can relate! I've got an 86 that is doing the same thing. So far: new coil, distributor, ignition module, stator in the distributor, and finally, new Electronic Engine Control. So I'll be watching to see what you come up with!!

Your problem sounds like the wires on the starter solenoid got put on backwards. If you have two large wires, and two small wires, you may have put the large wires on the wrong sides. One of the small wires goes to the coil +. If some of these wires got mixed up, then that would explain why it won't cut off. And the final blow was probably because the ignition is on all the time, you have burned up your points. You may have burned up the coil too, but you said you replaced that.

Well, I'm an engineer, so I'm hoping that i can handle two wires. The wires were in the right place all the time. I have no doubt about that. But I do believe the starter solenoid was shorted internally. I replace the points and condenser with an Accel high performance set I had laying around. WOW...it runs sooooo nice right now. Thanks for the advice.

"Suicidal" is why I only use Ford solenoids now. The last aftermarket switch only lasted 2 starts & stayed engaged.

Been here before
I had an 86 do this to me and now my 89 5.0L is doing the same thing. Replacing the ignition switch fixed my old truck and I am about to do the same thing to the truck I have now. I'm definitely just guessing, but it's a really inexpensive part and not to bad to replace. Hope this helps
