Ok guys I need some advice. I have a 92 Integra with a B16 swap in it with a VAFC. I have owned the car since 2004 and it has never ever really given me problems. The car hasn't seen much driving since 2008 ish. Everything on the car was great but when I moved to Florida in 2010 there were a couple bad rains and I had a passenger side floor leak so I got some water inside. I dried everything out and the car was great. One day in 2012 I went to start the car and I had nothing no power or anything I diagnosed it to the ECU being bad (Big burn spot on the board) I assumed it was probably due to the water so I bought a replacement. Installed the replacement and the car started and ran but I still never really drove it. I moved the car to a storage unit in 2010 and that's where it has sat since then. I went to pull the car out of storage yesterday and had problems.

The car started and idled great for about 10-20 minutes no leaks no misses nothing. I got in the car and was going to drive it around the storage place to see how it is doing and that is when problems started. The car was at normal temp about half way on the temp gauge and was idling properly maybe a little high. I sat in the sit and blipped the throttle and everything was good went to put it in gear but before I could it bogged down really bad threw a CEL light and the ECU started smoking. I pulled it open and the main capacitor blew. I have no ideas on what could cause this I'm looking for any ideas or suggestions.

 

hmm always though the 15 or 7.5A fuse was supposed to protect the ECU in a case like this ? (I'm no electronic expert tho) did those 2 fuses blow in the under the hood box ? how much water got in ? enough to touch the loom or just enough to seep into the ecu, is that VFAC hooked up ?

 

I couldn't tell you for sure on the Fuse but I'm pretty sure it didn't (the car is in storage an hour away right now).

A good bit of water got in but it was mostly in the passenger side floor board but there was probably an inch of water in there.

The VAFC is hooked up and has been since I bought the car in 2004.

I should note that the time from water getting in to the first ECU dying was a good bit of time.

 

Does anyone have any idea of where to start I'm completely stumped on this one.

 

Here are some pics of the ECU.
