Question about 1986 Ford F150 SuperCab

1 Answer

When the truck is running for 30 mins. it turns off

Then we have to wait about an hour or two before it turns on again. i went to a friend technician he told me to check the fuel pressure so he put on a fuel pressure tester and we drove around and it didn't turn off, we drove for about thirty minutes. but as soon as i took it off it started acting up.

Still sounds like a fuel pump! You could either have a wire rubbing and shorting out somewhere or it could be a weak fuel pump on it's way out.

Fuel pumps do funny things and you never know how there gonna go when they do.

I would first try running a set of wires from the battery straight to the fuel pump. Drive around see if that helps if it does it's your wiring. If not it's most likely your fuel pump.

Hope this helps!!!

After highway driving for 2 hours and stopping for gas the car would initially start and then stall, it would run again until the car cooled for 30 minutes.


Sounds like your coolant level might be low. At highway speed you probably have enough coolant and with the air passing thru the radiator keeps the temp down, but at idle not so much. Or depending whether you have a belt drive or electric fan. Belt driven, could need a new belt.

Car starts and runs. Once it's warmed up, the engine shuts off tried to start it again motor turns over but will not start. Wait a couple of hours then the motor will start again and then will shut off...


Wouldn't think sensor or computer problem , more likely an ignition module . When it dies pull a plug wire an check for spark ,i think you will find no spark . Just from my 30 years of diagnosing GM vehicle's this has been the #1 cause of a start an run till warm an dies an wait 20 min . to an hour an it starts again problem. But without testing to know for sure that would be a guess . Having a qualified an certified repair technician diagnose the problem is always the best idea.

Car will start run but when i get out and leave it for more than 30 mins it wont start back up and i have to wait over an hour untill it starts again


Will it turn over? it not your starter is getting hot and not working. If yes most likely your coil is getting hot and breaking down.
