Hello,
I have a friend that has a Ford pickup with the 4.9L striaght six. He is having some problems with it, like it will crank over, but will not start. He can leave it for 15-20 minutes and try it again, and it fires right up. My thoughs at first was either the throttle position sensor, camshaft position senser, or crank position sensor. But now I am sort of uncertain about it, any thoughts? He's had it to a mechanic and they cannot seem to find out the problems (pep boys ....as much of mechanics as you can call em, they specialize in oil changes and brakes, anything above that and they are lost :-P)
