7.3 wont start without help

[2broke2stroke]

i havce a 2001 f250 with a 98 model 7.3 shut it off and wouldnt start back 5 min later hv replaced cam sensor, hpop, ipr, icp, chip is out ,and new idm. I can give it a bump of either i know bad stuff but she comes to life , can drive it as much as i want and run good but if I shut it off and try to start back nothing. any ideas

I don't know man heres a does it smoke?

[2broke2stroke]

nope no smoke just starting issue other than that runs great .is there anything required to start and not to run ?

[CHUCK]

you gettin any fuel? No smoke usually indicates that theres no fuel getting to the cylindars

[2broke2stroke]

im assuming no fuel while cranking hence the no start , i dont understand why with a shot of either or gas on a rag it starts rite up and runs fine and for as long as you want. no spits no sputter no bad idle but if u shut it off and try to start back not gonna happen

I am just gonna throw a question out there for debate...could you have a faulty ignition switch?

I have diagnosed this before on a gas engine that when cranking, it wouldn't have spark. When you bump started it, it would fire right up and run fine.

I am not familar with the ign. circuit in our trucks but if there is "something" that should be getting power when cranking (idm?) and isnt because of a faulty switch, then you get it to fire on ether and let off the key that same "something" has power and runs the engine.

just trying to give you ideas!!!

Could be is there any way to check it can I cross silanoid with switch in on pos thanks

[Turbostang500]
