So heres the deal. I have an 83' F150 with the 300 I6 and it was running fine when i parked it a couple nights ago. When i tried starting the following morning, wouldn't fire. After a quick test I found out theres no spark coming from the coil. There is power going to the coil and i've tried replacing the coil itself, but nothing. Checked all the wire connections and even replaced the ignition module and still nothing. The big wire that goes from the coil to the distributor appears to be in good shape (it's only a year old). I've just replaced the ignition pickup in the distributor and nothing. I've run out of solutions and i'm thinking about having it towed to the nearest shop to see if they can figure out whats wrong, and i REALLY don't wanna do that. Do you guys have any suggestions? I really need to get it running for it's the only thing i have to get to work...

 

Power is present to the coil with key on, is it present with key in the crank mode? Thinking possible ign switch.

 

could it be the points inside the distributor? not sure just a guess. My grandfather had the same problem in his 1950 cady and replacing that fix it right up.

 

Thanks to the few that tried to help! unfortunately the advise i got didn't help, but I did find the problem. Turned out the ignition module did in fact go bad! Not only that, but all the ground points to the module got corroded! Would explain why the new one i tried installing earlier didn't work, lol.
