Help with wet pcm connectors

[LT_juan]

May be a long read: 1996 trans am. Had a misfire a while back (ses light would flash). Looked under the hood at night and saw where the spark was shooting out of one wire. Fast forward a few days , I got a replacement wire and went to turn the car on and nothing. What I did notice was that the ses light would not come on when I turn the switch on (you know like it always does but goes away once you start the car) so I bought an obd2 scanner and I got a link error ( scanner powers on, searches for codes but gives a link error). So I thought to check the pcm and switch it with one I have in the garage. I removed the harness connectors and they were wet. Soaking wet. I shake them and drops of water come out of the color coded plastic pieces where the pins are. The pcm pins are also wet. I must have re installed it wrong a while back when I undid the obd1 conversion to pass smog. Question is , is my pcm fried? Suggestions on getting rid of all the water on the connectors? Blow dryer?

I would put the PCM in a bowl of rice of if you have some dessicants to dry it out. Fix your sealing issue that is allowing moisture to get there. Use a eletrical cleaner on the PCM connectors once the have dried and apply dieltic grase to them

Like Chris said. If its wet. the pcm won't be able to communicate with anything because signals/pulses will be going crazy.

Had same thing on my old 95 happen. I pulled it. let it sit and dry then it fired up. I was young and dumb. And shot it with a power washer....live and learn i guess lol

Thing is I know not to power wash the engine bay on this car. So I need to figure out where water is getting in there from. It rained a few days between now and then. That must have done it.

I took my car to the power washer and never opened my hood and got a flashing ses lol

Water will run down the cowl. And drip into the area where the pcm is(if the rubber seal is worn out on it). I replaced the one on my 94 because it was getting pretty bad(25.00) and laid a line of rtv sealer under it for good measure.

Will do the same. Thanks
