d90 won't start after pressure washing

I should have known better, but I wanted to make sure all the road salt was gone and pressure washed my '97 D90 SW. Now it won't start... It has a valet remote start system that might be part of the problem. Engine will crank, but won't start. Have tried using blow dryer on elecrrical components... any suggestions besides "don't do that again!"? Thanks!

If it's the same with mine, most likely you've gotten moisture into the coil connection(s) Take the coil wire off the coil and spray it (and the other surrounding connections) with WD-40 On mine, that displaced the water and got everything running again......Hope this works for yours

Road salt in FL? Still haven't seen any this season up here!

Did you really pressure wash it? Why not just hose spray it???

I always heard if you're gonna wash the engine leave it running, does this make any sense to anyone looking at this (sorry for the highjack). Also, you get any water in the dist. cap?

Yeah, I normally leave it running if I am washing the engine. He couldnt have water in the dist cap, he doesnt have one.

You might have water in on of the conectors by the coils at the rear of the engine, maybe you got some water in the ECU under the box on the right side of the engine. Past exp was taught me that it usually drys out in short time so it should start soon hopefully :D

Why would you have the motor running? Water's a pretty good conductor and it does wonders getting into the intake.

Your computer is wet. Turn everything off, and shake the water out of the bottom of it through the drain hole. Leave it plugged in if you can. The sure way to tell is if you have a check engine light when you first turn on the truck that goes off after a few seconds. If not, you got the computer wet.

Next most likely is the crank sensor.

Any luck, Bruce, on getting your D90 started? I'm curious what worked.

Pressure wash force water where it is not suppose to go,
search for those places and dry.
Good luck.
