Fried ECU? Can't find a thread with this problem.
SO.... It's been raining a lot here in Ga and I noticed a couple of days ago that the area where the homelink would be was leaking water. Been working a lot so I haven't had time to look into it, figured it was no biggie. Had to drive it to work today, it was light rain all day. I hit a little trail with a little mud on the way home . Pulled it in the garage this evening and it started running very very rough the HDC warning light came on check engine(not blinking) and the tachometer didn't work. Parked and turned it off then tried to crank it back up. It acted like it was carbureted and cold. Had to feather the gas pedal to keep it running. I've done the three amigos fix and flushed and everything has worked great. It's pretty much undrivable. Ideas?

There will be pending codes.
Pull the pending codes with an OBD-II scanner.
Even without a check engine light on there can be pending codes.

That's what I'm afraid of. If that is indeed the case is this a good solution?

Diagnose, diagnose, diagnose.
Have seen only one ECU blown in my electronic life, because the battery was reversed. They are very sturdy and reliable.
Checking its connections and proper signals and voltages will mean a lot of skilled labor. That is why typically pseudo mechanics tell owners the ´computer is bad´ and after replaced with owner money, problem stays.
Best is to start with schematics and fuses, then borrow another and confirm.
It's been like 20 years now, they do not manufacture automobiles anymore. They make computers with wheels. Takes an electronics expert to diagnose.

So i bought an ecu and bcu like an idiot without looking back at this thread first. Pretty sure you are all correct. No change. I've checked all the grounds,not really sure where to go from here. I'm more of a grease monkey but i know my way around a multimeter and a BASIC understanding of electrical systems just not sure where to start with it. Any suggestions? Don't have the money to take it anywhere.
