pressure washed the engine, now it wont start

Okay, need a little help here. Pressure washed the engine all off today, didnt get to crazy, or anything, but, now it wont fire at all. Pulled the icp sensor plug, blew it out, pulled the other sensor my edge plugs into, blew that out, didnt help. The only one I havent played with is the cps plug. Think thats it? Heck it wont even fire now. I have the hood up and letting her sit all night, hope that cures it. Checked and no water in the intake, i give up on where to look, help!

Thanks!!

I've decided that after all of the problems various people have had after washing their motors, mine is never getting washed EVER AGAIN.

My vote wold be CPS,IDM,IPR or the electric harness's in the engine bay. Dowsing the wiring with isopropy alcohol will help dry out water
in hard to dry places.
good luck!

okay, used the compressor to blow out all the electrical connections, the cps, ipr, etc etc. Put propy alcohol on everything and letting stuff dry out. Went out and tried to start, and nada, just cranks over. Popped the fuse box in the engine compartment, and they are all good, except the 30 amp that powers the trailer battery charge.

Any ideas anyone?

Does the tach register? Maybe you fried the cam sensor.

i just found out if you want to power wash your moter to use cold water.moter can be warm to the touch. you dont want to create steam as steam is the biggest problem with sensers. steam gets into tight spots very easly compared to water and it creates problems.. i used plastic bags to cover alt. and the fuse box on fender well.. i power washed under the hood as soon as i was done started truck and drove it for a few miles to dry it off..had no troubles.. just thought id add my thoughts as most of you probly already new this..

So why power wash your motor unless your in a mud bog or theres a oil lealk an dust an the engine is real dirty. CPS sensor could be the culprit though. I have yet to use a powerwasher on my truck an have not ever had to put a CPS sensor in yet knock on wood. Power washing is nice but the pressure those thing put out can do alot off damage to electronic stuff.

I always keep my engine clean and shined up, just **** thing I guess, but I like popping the hood and seeing a nice clean engine. Also makes troubleshooting leaks easier. Your first problem was using a pressure washer, you shouldn't need more than a hose with nozzle on the end, soak the engine with simple green or the purple stuff. I don't use the degreasers because they will stink for a week or so. Cover the alt. and PS resivour cover. I do it twice a year in warm weather, clean it in the morning and leave the hood open all day to dry out.
Chances are if you tried to start it and a connection was wet you probably already fried it. If water is in the connection it could take a week or so to dry out. I would take each one apart hiut it with some air, apply dielectric grease and reconnect and then try to start. If this don't work you have fried something.

okay found the problem, thanks to those that responded. It turned out to not be a wet sensor at all. The sensor at the bottom of the hpop, i believe this is the ipr, has a gold cover and the wires hook up to that. My gold cover thing has the ability to move (somethings missing here) and the pressure washer rotated that twoards the passenger side. The gold cover and wires can slide off the back of the ipr rod, and threads are showing. Can someone send me a picture of what is supposed to be holding the sensor from sliding? This may explain the weird roughness of my engine from time to time over the last month also, ugh!

Some good info in this LINK on working on IPR's and building a special tool to remove. Don't know if it answers your exact question.
