So I buy an 86 F150 4x4 with the 300 I-6 from a guy who knows nothing about cars at all. For 600 bucks I pick up an ugly, yet decent pickup with a plow, 4 new tires, and a new 1 bbl carb. He tells me it won't start, and he thinks the starter is up...I tow it home, behind my uncle's Chevy (puke!) and yank the starter...Bench test it, and sure enough the bendix is junk... Looked over the starting system and decide my 3 year old son could have done a better job with the wires...Replace the whole thing. Excited, I try to fire and nothing cranks over and cranks over...you get the point. Moving on I check the distributor and the wiring is out of sequence, so I pulled the cap, checked the pickup coil and decide to replace that and the ICM Module...by the way wasn't getting a good spark off the coil... Changed the coil, wires, and plugs, made sure I had the distributor set right at TDC, everything was in time. Tried again, nothing...get out the test light and find I had a fusable link that was basically green dust in a rubber protector, repair it and Well, now at least the headlights work. Change the fuel pump just to make sure it was good, and nothing...To the point, I got the test light out and have no power to the coil Yellow/Blue wire 3 inches to the harness, and nothing to the Green wire, as far as I can chase it. Any Ideas... oh and by the way...I should mention, hope you never need a power steering belt pulley!

 

im sure you've tried this, but make sure the battery cable terminals are good and clean.........also check to make sure the ground cable to the batt is in a good spot.........oh yeah......starter soilenoid.......could be bad........its located next to the batt on the fender..........good luck man

 

I forgot to mention, all new battery wires, terminals, starter solenoid. I have a seasoned mechanic coming today to look at the thing. Maybe he will know what it is.

 

I'm having the same troubles with my 85 F150 300ci. Cranks and cranks but will not start. A few times it ran for 20 seconds but then died. Just like you, no voltage at the coil (Yellow-blue and solid green wires). Did you find the problem?

 

Are you getting fuel to carb? Did this guy put the carb on? Sounds like he made a mess of the starter, probably messed up the carb as well.

4dview: Turns out the Yellow blue wire was bad at the plug in adapter to the coil...Got a new one, pluged it in and thats all she wrote. I used a test light and tested back in the wire to the ICM and that was the only spot bad.
Nudgey: The starter is brand new, and how do we qualify, someone makes a mess of a starter? the carb was brand new when I bought it, and by the way...it runs great now...so, before people judge what I did, read the posts.

 

Only trying to help, no need to be like that.

 

Turns out it was the ignition control module after all. The ground for the coil is supplied through the ICM, thus no voltage is supplied to the primary side of the coil when the ICM is bad.
