79 with 94 efi 302 no fuel/spark
ok this is what i've done, i have a 79 f150 302 that needed a new motor. my dad just so happend to buy a 94 f150 302 to strip it for body parts for his 93.
with the whole truck at my finger tips i decided to convert my 79 to efi.
the swap is done but no fuel or spark. i've read the pcm and i get one code ''111'' ''system pass'', and i have fuel to the rails with pressure. now i just read on another thread here that a guy had a similar problem and it turned out to be the ICM, could that be it? it may have been banged around on the floor while i was trimming the wiring harness.
and the parts truck was running when i got it, i drove it to my house.

have you checked all fuses? Are you using the stock engine harness spliced into the 79 dash harness or did swap in both dash and engien harness? What did you "trim"? I honestly have no idea but I'm sure others would want to know more details on what was all done to better help you.

fuses are good.
i got 4 wires coming through the fire wall, all to the ignition switch.
the harness on the engine its self i have not touched. the other harness under the hood, i guess ill call it the power disribution harness. i trimed everything unrelated to the engine, headlights, windsheld wipers, horn etc.
i have all the wiring diagrams i need(79 and 94 trucks), ive checked everything at least ten times now.
the pcm pwr/fuel pump relays work, i know the computer working because if i start unpluging things it tell me through my code reader

thanks for the help, i got her going last night. what it was, i had it turning over on the 79 starting system, it seems the pcm wont fire the icm or the injectors cause as far as it know your not trying to start it, it was one wire(always is lol) that needs power in start and bam! now i just got to make the wiring look good.
