Truck starts great in morning. After driving and engine gets warmed up if you try to start it requires excessive cranking. 2002 xl 4.2 ltr 6 cyl

 

i have the same yera and motor in mytruck.cant say i have experienced this problem,but do you have a check engine light on.almost sounds like a sensor issue.

 

Thanks for replying. No check engine light. This problem has been going on for months(Nov,Dec). In January i had the motor replaced(remanufactured), along with MAF, IAC, Coil pack. Dealer says it is the fuel pump, that it lost pressure where they monitor at the fuel rail. With the key turned on the fuel pressure reads 35 psi right away they say it leaks down. My problem with that is every morning or after sitting many hours the engine fires immediately if it is warm it requires excessive cranking to fire. Before the pump theory they sold me a new key saying it was the anti theft sysytem. So im not completely sold on the fuel pump being the problem and dont have complete faith in the dealer or any mechanic for that matter-still looking for somebody.
