Hot start issues
I have a 2003 E150 5.4 wagon. About 70k miles. If I drive it long enough for it to get fully hot and park it for about 15 minutes to a half hour, it sometimes fails to start. It seems to be a fuel issue as starting fluid sprayed into the intake will allow it to run. After a failure it will start after 5 to 20 minutes of trying every minute or so. Never throws a check engine light. Once running it has no issues. Never stalls, runs strong and smooth. The fuel filter is new. The van is used about twice a week and has sat for as long as a month. Before I replace the fuel pump, are there any other bits that could fail and cause this? Collision sensor? Some other piece of hardware that could overheat and shut down fuel delivery? Thanks in advance,
John

I've lived through a bad cam sensor that would malfunction when hot (again - not in a Ford), but not throw a code. Not sure why, but it was well documented for that vehicle.
The only real problem with chasing down the sensor issue is that you really don't want to start just throwing money out there on sensors when that may not actually be bad. I isolated the sensor problem by cooling it off and the engine would refire. Not sure if you could try that due to the location of the sensor.
