I have a 1988 F-150 5.8 that on occasion will not start. I can be driving it and stop for something, get back in and it will turn over but act like it is not getting fuel. I can let it sit for a few hours and it will start back up. It does not seem to have a certain pattern of when it does it. "Cold or Hot". Any Ideas???

My 85 5.8was that way,but it was a 4 barrel and would flood occasionally. Maybe try to disconnect the battery,to see if it will reset the computer.

I have tried that to no avail. I changed the fuel filter this weekend and it seems to have not helped either. Thanks for the suggestion.

That's a classic symptom of a failing ignition coil. Is it slimy with oil?

I'd be willing to bet that it's the ignition. My 86 f-150 with the eec-iv system in a 5.0 did this constantly. Wouldn't start, or would be running going down the road and die. Let it sit for a while, usually 15-20 minutes and it'd start right up. Put a fuel pressure gauge on it, normal, put an ignition module in it, same crap, quick wired in a different coil to test ,same thing, put in a new distributor pickup and walla, problem solved, parts store even stocks it, said that it was a common problem and only around $40. That's what I'd start with.

My suggestion is that when it IS acting up, ck for spark/fuel. EAsy enough to do if you have the necessary tools.
EAsiest is spark.
Then you can confirm/deny certain problem areas of the no start condition, without shotgunning parts at it that it doesn't need.
Seen literally hundreds of vehicles come into the shop where customers have thrown every part at the vehicle EXCEPT the one it needed, just because of advice , etc, internet chat lines, you name it.

No flames intended here, whatsoever, just trying to save you some pulling out of hair, and some bucks.

Common as hell for TFI modules to take a dump on that model/year of vehicle. Also lots of other things. (list would be too long to type up in one sitting).
In either case, good luck.

I did do what you suggested about three weeks ago and did have spark. I took the truck to the shop and they ended finding the the relay on the fuel pump was acting up. Thank you for your comments and suggestions.
