hi i have searched for ever, i have a 01 f350 7.3 and wen i turn the key it wont crank and no wate to start light. i only have 5 volts at the ccp and the crank relay. ALL FUES ARE GOOD! getting soo mad. i have 12v going from the batterys to the key switch. BUT! if i jump the 2 wires that should crank the engine it does nothing??????????????. ANY INPUT WOULD BE GREAT.

you are not getting power to your PCM, causing a no wait to start light an no crank. You sure your fuses are all good? one could be bad, causing no power to the pcm.


Other thought is a bad pcm.

i know i thought for sure the fuse would be bad, ok one right bellow fuse 15 is a 15v amp i have no power there. dont know what it does. i live in calgary it is -33 and i am getting soo pissed off.

I dont know what it does either. as I have no truck in front of me to reference. If all your fuses are good, then I would say for some reason your PCM is fried.

maby i should try to put fords scan tool on it see what happends?

[HVAC SuperTech]

you can, but i am sure you wont get any commnuication with the PCM. try it tho, and see what it says., maybe it will show something.

[power stroker]

could i jump power to the pcm?

I just did some work to mine, except it was blowing the PCM fuse. In my case I needed a new fuel heater, but I read on IATN that these trucks sometimes leak water at the windshield and the water will run behind the dash onto the fuse block and cause some corrosion. Might be worth a look.

I dont think, nor would I try to jump power to the PCM, if its still good, you might fry it in the process of jumping power to it.

well idk what truck you got or really anything about the electrical on the new ones, but did you check fuses in BOTH the cab and relay box under the hood?
