so i decided to power wash my engine bay and chassis today. i just wanted to clean up my truck before i started a sas swap. soo after i finished spraying it down i started it up and it started fine but after about 30 seconds it died. i couldn't get it to start again.

so i am not getting any spark and i think it needs a new ignition module could i have damaged the module or is it just a coincidence it failed after the wash?

Check again, it needs to be completely dry. Id be willing to bet that's your only issue.

That happened to me once on my 95. Problem was my air filter was soaked and it screwed up the mass air flow sensor. I'll never use high pressure again on a vehicle with lots of sensors, relays etc under the hood. Like liltimmy said check the dist doesn't take much to screw em up

Can you here your fuel pump turn on? If not you got the relays on the drivers wet. I have done this and it does not take much to corrode them. there like $10-15 just replace them

I had this happen a few times after a car wash, Usually what would happen was water would leak down onto the ignition coil and get in the connection there.

I work at a car dealership, and after the used cars get a safety inspection they go to detail before they go on the lot. Those idiots screw up soooo much crap. All kinds of crazy problems after they clean the engine bay.

This happened to me so many times on my 91 5.0 pickup, if you know your cap and rotor are dry, it would be my next guess...

I consider powerwashering a easy way to find a problem in my driveway as opposed to the middle of a creek or wash. I'd rather find out about old crusty electronics or vaccuum in the comfort of my garage any day of the week...
Matter of fact. I'm ordering a new shift sensor for the tranny right now because of this. I feel lucky.

Well done. Like they say, every cloud has a silk purse in the bush.

Or something...........

i guess there was so much resistance in the wire it was easier for the spark to jump to the rubber hose which was wet at the time. i think i still have the wire lying around i could put it back on a take a shot of it arching.
