Howdy

Been a while since I posted, but it's been a while since this truck has given me any grief.. been a decent truck, aside from getting super crappy gas mileage (never figured that out) and sounding like **** (exhaust leak).

Anyway... got a '96 f150 300 5-speed that suddenly doesn't want to start when it's hot. The starter motor engages and rotates the motor solidly and forcefully, but it won't fire up. I smell strong odor of gasoline almost immediately, from inside the cab- but can't really smell it anything where, getting out of the truck and checking for fuel leaks.

If I let it sit for 20-30 minutes, it'll fire right up no problem. Runs fine otherwise... just gave her a tune-up (after the problem started, hoping that would fix it). I haven't done the fuel filter yet, because I hate getting squirted in the face with fuel, but if I'm smelling a strong odor of gasoline when it's rotating, that would lead me to believe it's NOT a fuel pressure problem, nor pump.

ICM? Some sensor? The engine light has been on for a while, also... so there's that. I did the cat converter and O2 sensors about a year and a half ago.. but I suppose anything's possible.

Do you have spark when it won't start ? PIP, coil or ICM will act like that just before they go south entirely.

x2, PIP or coil

Well let's hope a new coil does it, then... 'cause I do not have the time or patience for a PIP sensor right now.

For the collective:

This ended up being a bad temp sensor. The sensor was reading way colder than the truck was, so running super rich. Flooded the engine, when hot.

All fixed now.

Glad you fixed it. The same issue happened to me. Frustrating to know it was a temp sensor makes the truck useless.
