First off I am no good with wiring. I need some help figuring out what's up with my truck.
1986 f150. Was fuel injected
Now has a carbd 302 with random wires cut from the previous owner. It ran good until a few weeks ago. Parked it. 20 mins later it wouldn't start. But cranked normal. Getting fuel but no spark. New distributor,coil,ICM,plugs, and I replaced all the wires from the ICM to the coil. Still nothing. Has the duraspark II system on it. With the blue grommet ICM. I have found so many different diagrams I don't know where to start. But it ran before hooked up like this. Red and white wires on the ICM were both hooked up to a 12 gauge white/blue wire, which had a jumper wire to coil positive on it also. And the Orange,purple,black were ran to the dist. Green to coil neg.
on the starter relay a red/blue on the s terminal. I terminal has nothing. Hooked it up a few different ways and the coil and ICM get way to hot with the key in the run position. From what I've read it needs a resistance wire. Where would I find that and how can I hook it all up right.

 

Before you get too twisted up, see if you can lay hands on another Duraspark box. Or buy a new one. They can and do fail. At worst you'll have a spare. Various ignition modules on a variety of brands (even some motorcycles) are famous for working fine until you shut off the engine which mysteriously won't start up again. Durasparks are no exception. Many folks out there carry a spare Duraspark box around with them. Or a later "TFI module". Or a Dodge ignition box, etc, etc.
