1989 F150 300 6 starting problem when hot

[leaster1939]

Truck starts fine when cold. Will restart right after I turn it off. If I let it sit for 10 minutes, or so, after it warms up (say going to work) it will not start until I open the hood and let it sit for another 15 to 30 minutes. In the past couple months I have checked the starter, cables, battery condition, replaced dist. rotor, wires and coil. When it does start, it runs great. (only 164000 miles). EGR was replaced about 10 years ago. Vacuum line to EGR has been plug off. I am still not sure if it is an ignition or fuel problem. It sounds like it is trying to fire but may not be getting fuel.

Next time it does it, check for spark. More than likely it is the ignition module failing when warm. Ford was well known for that.

Thanks, you are probably right as this whole thing started with a caroded ignition wire to the coil. The sender part (external part) was replaced a couple years ago. The mechanic told me then that the pick up (internal)will probably go next.
