It might be an issue with either the crank sensor that acts like a heat sink when hot and causes a change in internal resistance, causing it to not give proper feedback to the engine computer. Check to see if your tachometer needle is moving when cranking-if not change the crank sensor. If it sounds like it wants to start but won't, it is a fuel issue-either leaking injector O-rings or a fuel pump that has too low pressure as it heats up can be checked at the fuel rail with a pressure tester.

Wont start after running for a while. service lights work, radio, headlights but wont crank. just replaced starter, got new battery about a month ago. after 5-8 hours car starts with no problems.


Hot does make a difference. You say it won't start, but does it crank and not start, or not even crank? If cranks but will not start, any electrical part may fail as it heats, and when you shut it off the engine gets much hotter since coolant is no longer circulating. Thus, a marginal crank or cam sensor, or coil/ignition module may work while cold of while engine is running, but fail when you first turn car off.

The parts you replaced don't typically fail due to heat/cold cycles.You need to see if it might be the ignition coil.Make the coil easily accessable(take of the engine cover).Have a 12v test light and some sort of spark tester handy.Start the engine,let it run until it quits.See if you have spark at the coil.If not, unplug the low voltage connector on the coil,and put the test light across the connector,and crank the engine.The light should flash on and off.If it does,replace the ignition coil. If it doesn't flash,you may have a bad crank sensor,but this usually won't make it shut off,instead,it will cause it not to restart after heat soaking for a couple minutes.(I'm betting on the igniton coil).

Its cold and engine will crank but wont start, could the fuel pump went out ?


It could be the fuel pump, but try the battery first, it is less expensive and if that's not the problem you can normally take it back. Then maybe try tune-up if you have not had one recently. These are least expensive options as opposed to replacing a fuel pump.

If fuel delivery isn't the issue then check fire. Fords of this era are famous for ignition modules acting goofy with heat. Works nice in the cold not so nice in the heat. Yes...like a Panda Bear. Change your module and you'll be off and running.
