Exclamation Engine won't crank or start after power washing

I am working on my friend's truck, it is a 2003 Ram 1500 4x2 with a 4.7L. He power washed the engine while it was running and then after shutting the engine off it will not crank or re start. The battery was replaced, the starter was replaced and the ignition switch has been replaced. I have also checked all fuses and they are ok. There was one blown fuse for the radio but that was replaced and the radio works now but still will not crank. I replaced the starter relay and it still won't crank. Any ideas please???

Thanks

If its had a while to dry and still wont start stop throwing parts at it! WOW EXPENSIVE!!!! Get a can of WD-40 AND SPRAY Anywhere water can cause problems. plugs, coils, wire conecters etc. WD stands for water displacement,by the way. If you have to even use a hair dryer to dry things out alittle.

Problem fixed. Found the engine ground cable to be loose. Tightened it up and everything works great now. Starting normally. My buddy wanted his started replaced anyways since it was original. The ignition switch was sticking and needed replaced, and I had a new relay laying around so replaced the starter relay with it just to rule that out. I ended up checking voltage at the starter B+ cable and the solenoid trigger wire - both were 12v which is what lead me to check the grounds. The bolt holding the ground cable to the engine block was loose.

Yeah I got bit by a bad engine ground while diagnosing a no-start. That one ground will make the car do all kiinds of funky stuff and get you to chase ghosts.
