Ok before you spend any money on a distributor try this. It may sound funny but just try it. Unplug the wires to the ign. module and crank the engine with them unplugged for about ten seconds, then turn the ign. off and plug in the wires to the ign. module and then go back and try to start it and see what happens. I have had mustangs do this and then they start afterwards and I dont know why it works but it has many of times. It may or may not work but its worth a try.

 

well i got a spark now. i had replaced the connector on the tan/yellow wire going to the ign. coil but i didn't replace the plug on the red/lt.green wire as i was reading voltages from it with the meter. so i decided to replace that today as well and found that the wire inside was very black. i cut down about 2 inches of wire and it looked like copper wire again and cripped on new connectors to both + and - wires and got spark! w00t.

now just wondering, i can crank it over and it tries to run (sounds great with that RV cam in there) but dies pretty quick. i dont have o2 sensors yet or full exhaust. just headers on it right now. should she run ( i'm guessing ruff as hell) without all that or is it doing what its supposed to do and just dying after i'm done cranking? i'll be brushing up on the fordfuelinjection.com site to verify as well and i will be getting sensors and finishing the exhaust this week. thx for all your help guys!!

 

When I did my first efi motor swap I had the same no spark issue. Turns out the 12v Ignition source I used for my ecm would go dead when cranking. Key on engine off it showed 12v which kept throwing me off because when I was testing everything it appeared to correct...except when I cranked it the ecm lost power. I moved that power wire to a correct 12v source and it fired rite up.

Cliffnotes= check all 12v leads with key in crank position also.
