no crank

2000 7.3 psd 4x4

I have the exact sam problem!!! Some as$hats tried to run my truck thru a car wash, broke the sunroof bezzel, after a rain water filled the floor board/drivers side.

Will not turn over.

1. all fuses good
2. will start if I jump the solinoid on the passenger side(no power to the small wire when ign sw is turned)
3. power is coming out of the ign sw on the steering column
4. no aftermarket alarm system

Is there a factory starter interupt?
does the starter wire run thru the pcm or bcm?

When the truck got rained on, it was turning over on its own randomly(key off), so I disconected the batteries and waited for it to dry out. reconected the batteries, started fine, later that day, no turn over.

sam problem this guy had:
wont start

ok, solved the problem. Turns out it was the fender mounted solenoid.

her's what it was doing:
the solenoid had a short, the small post was slightly grounded(three posts on the solenoid, 2 large and 1 small), when I would run a jumper wire to the small post it would spark really big then start the truck, when I would try to start the truck using the ign switch it was grounded just enough to not blow the fuse, but kick a circuit breaker? and the small wire going to the fender mounted solenoid would not produce power for like 5 minutes(breaker??) I am not sure if there is a breaker, but when I noticed the large spark when I jumped the solenoid/relay I thought it may be bad and drawing too much of a load.
