1978 Ford F250 Pickup Coil Replacement! (Crank but No Start) (Part 8) 

Good job! I have had 20 of these era trucks. The silver box on the D/S fender well is almost always a culprit. Keep an extra one under the seat. But the spark at the release of the key may be a good tip for diagnosing (also an ohm meter if you know the spec and the problem is not intermittent). By the sound of your starter, you either have a low battery or your ignition timing is a little too advanced. With the pickup coil swap, timing should be checked anyhow. Sometimes only on the 351m/400's for some reason, the roll pin on the distributor shaft shears at the cam driven gear. The symptom would be a no start also. Popping the cap off will reveal that the rotor does not turn while cranking the starter. In that case, the distributor would have to be removed and a .50 cent pin replaced. I also see you have the big front axle. The Dana 60. Everyone wants that axle. Perfect for a 12 valve Cummins swap...I see you have mentioned a diesel swap below in the comments. Good luck with the project. Do drive the truck and enjoy it before tearing it all apart if you can. The projects are always bigger than one anticipates and life gets in the way sometimes.

Great video. Thank you. My 77 f100 with the 302 is the same set up. Had been having issues starting and or stalling out. After changing all of the other stuff like spark plugs and wires, ignition coil and the ICM, this was the last thing since it wasn't a fuel issue. And it worked. Fired right up

Your awesome! Thanks for the video . Been replacing parts for 4 months

You got it, thanks, you help me a lot,

Very helpful thank you!

maybe the camera angle made it seem off. but the center of the coil has to be centered on each of the rotor fingers. there is elongated holes on the pick up coil mounting holes to allow you to move it around.

good job man

Good Job

Nice work bro!!!

Thanks 👍🏼

An easy way to check your pickup is to carry out an Ohm check on it. 0-400 is a no go, and anything above 1400 is a no go as well I believe.

Thanks man. Fingers crossed this is the problem with mine. I have 12.48v to the coil with key in on position and 10.5ish when cranking, but I'm not getting spark. This tells me that the ignition is sending power to the module and the module is sending power to the coil, but the sensor is not sending spark to the spark plugs. Replacing the sensor tomorrow and I will update if it starts my truck.

🙌🙌

What ended up being the repair to get it fired up? Just replaced the mechanical fuel pump and no go. engine fires right up gas str8 into the carb tho

Cool truck! What are you plans with it?

I have a 1979 F250 4×4 Gas 4spd Manual. I haven't been able to get it to start since buying it almost 2 months ago and driving it home. I've looked all over the internet but I can't find a darn thing. I've been lead to two possible culprits after replacing the fuses, regulator, coil pack, and battery. Either I'm having a grounding issue or my distributor. I'm getting air and fuel in the carb, when the battery has a full charge the alt will spin, but no spark. I'm pulling my hair out trying to figure out my issue.

How's the little roller pin come out? Looking at it like how tf did he get it out lol

Is that a oem coil
