Hi
I have a 2003 F-150 super crew 4wd with a 5.4 motor. Once in a while it doesn't want to start. It will just keep cranking for awhile then fire. If I tap the gas when it is doing this it will fire right up. I have checked the fuel pressure and everything seems to be fine. There is no check engine light. Could it possibly be the TPS?
Thanks for any help
