Intermittent starting problems 95’ 4.9L

I’ve got a 95’ F150 with 4.9L. I’ve owned it for about a year. This truck seems to have good days and bad days. Some days it starts right up, some times it will just turn over but won’t crank. I’m at a loss with where to start looking for issues. I suspect something electrical since it’s all intermittent issue. Has anyone else dealt with an issue like this?

I have seen it on this site with a bad PCM.

By the way turn over and crank are the same thing.

It is about to hit 300k miles. I’m gonna price some parts to throw at it I guess. I wasn’t sure how to best articulate the symptoms. I guess turn over/crank would be the rotation of the engine and firing or starting would be a running engine?

Running is running without outside assistance.
Turning over and cranking are the same thing - without running.
Somewhere in between is "trying to start - but won't run"

Have you either used a paper clip to pull codes or done it with a code reader? To see if it has any stored codes that may give you pointers? You may not have a check engine light showing but the computer will still store codes.

I don’t believe mine has an OBD2 connector. 1995 model.

Nice. I’ll probably just buy the scanner. I didn’t realize that was an option. That will make diagnostics much easier. Thanks for the help everyone. I tried google before posting on here but didn’t find any of this information. Now I have suspected the ignition control module to be bad since it is intermittently running when it wants, thanks to Subford. I figured since the only intermittent problem is running and nothing else I narrowed it to the ICM instead of PMC. I did jump the gun and bought one so I’ll plug it in and see.
