2001 Ford Ranger manual transmission 3.0 V6 doesn't start when warm. Truck starts great in the mornings but I drive 10 miles turn it off and it won't restart for another 3 to 8 hours. Sometimes I can hear the fuel pump when I turn on the key at this time and sometimes I don't. But either way it still doesn't start when warm. Check engine light is on but have not gotten a read. As when I tried to get a read nothing registered as if there was a wiring problem to the plug-in for the engine light. Any suggestions I am duped. And I have checked every fuse and every sensor and every relay the only time the test light goes out is when I unplug number two fuse underneath the hood I haven't quite figured out what that goes to.

 

Temp sensor?
