Got truck in some water but did not sink but half of the motor--replaced cam sensor and still will not crank--what might it be?

The very first thing I would do is to see if the engine chan be turned over by hand. Use a breaker bar and a socket and try to turn the engine over manually by placing it on the crankshaft.

You may have hydorollically locked the motor.

It will turn over fine by the ignition switch--it just won't crank up--what would be the difference in doing it manually!

We had a communication problem.

Cranking and turning over are symonomous.
I thought you meant no crank.

Safe to assume there is just no spark on this?

Yes Sorry.

Wine and women;-) know what I mean :-).
Uhh it is the holidays!
Let me do a little research. And I'll re-post, I am not familiar with the diesels, other than the diesel father's mysterious death.

I am trying to get hold of another mod that is, hoping he can help out, I will make a post to alert a few other mods that may be of assistance.

Hi there,

First thing to do is a compression test, It is a real possibility that you have compressed a rod, Now this will not stop it from running but if you have a deficient compression it is a waste of time going any further. Apart from that, back off all the injector lines and crank, you should have fuel pulsing, if not there is a problem with the injector pump. Start there, now I will be around on and off over the Xmas break so I will try and catch up with any posts you make.
