ECU, Immobilizer issues

While running I got my master key wet. Its not the first time its been wet, but I know its bad to do anything to our keys. I might have even had static built up from running 10 miles.

It gave me the blinking green light while driving home.

All fuses checked-they are good.
Grounds are all good ( battery to chassis, engine to chassis)

I tried again later to it wouldn't crank up. It would turn over but not stay alive. I tried again 10min later and it struggled a little, but finally came to life. I noticed the blinking green light went away, but to be replaced by the SRS light.

While it was alive I took it to Orielly auto parts to check out the alternator. Its good and so is the battery.

When I got home I turned the car off, and restarted, still struggled, but came alive and now all the lights are gone..tried it 3 times, came alive every time but struggled.

Wth is up with that?? My guess is funky ECU, or a dying starter. The key itself would cause it to struggle so much to crank would it? I recently topped off the battery with distilled h20 FYI.

I dont what that was just all about. Just got back from the dreaded gasoline station, she fired up quick this time! It must have been the water on the key. No CEL, SRS, green key--nothing. Back to usual I guess(whew!)

All that stress, false alarm. I need some wood to knock on!

Ugh its back!! All lights are off. Fuel pump pressurizes in the "ON" position. I will crank up everytime but stuggles like a motha. I noticed the tachometer and speedometer flick a bunch and the odometer displays all zero's, then goes away!

Im still mobile lol. Every crank just feels like im killing something.
