ok this morning i had a customers truck towed in with a no start.There is a po340 cam sensor fault and i have one on the way from ford but i also have other codes.p1670 ef feedback signal not detected,po475 exhuast pressure control valve fault,p1316 idm codes dected.the customer told me he put a used comptuer in a couple of years ago but thats all i can get out of him.he is telling me for the past couple weeks the truck has been running terrible so im hoping the cam will at least get it runnuing...any clues on the other codes guys?????

ok i put the cam in it and still no start...codes p1670 came back. i clear that and run a self test and i get p1663 and p1667 now. my feeling is a bad computer but i am afraid that its possible got a wire rubbed through under the valve covers.i also have no blown fuses.

Well I found out by running a self test there was a prob with # cylinder so i pulled the valve cover and replaced the gasket and harness inside the cover and it started right up...after about 5 min it died like someone just turned the key off!!!! Once it cooled down it started back up but with alot of cranking.My icp was showing good pressure and i had a good strong battery power.my origional code p1670 came back with another self test. Any help on this one???I'm bein told by a ford tech i know that i prob have a bad injector drive module.i was hoping to get another opinion
