ECU Brain Dead? Car not turning on for some reason
My car has sat in the garage for the past 4 days because I was waiting on a part and couldn't drive it (Oil feed line to td04 started leaking). I drove the car into the garage and it was fine.
The part is back on the car, but now the car won't start. I tried resetting the ECU or changing the map with the Accessport, but it can't connect to the ECU for some reason (with or without green connectors connected)
also, the Check Engine light flashes on and off briefly like there is a bad connection, like a flickering light rather than a serious engine problem
The car cranks fine, but won't fire. The fuel pump doesnt prime or anything when I turn the key, just all the electronics work
Not really sure what is going on here, I didn't touch anything electrical during the fix
someone help me out here please

I have the OEM security system and this is a key from Subaru that was programmed by GST.
If it was a security issue, wouldn't the car run for a few seconds then shut off? That's what I heard what would happen if something was bad there
Its weird, I mean the car doesnt even try to turn on; All i can do is run accessories off the battery

Additional Info, Same problem:
So the car turned on, ran, but it didnt sound very good. Idled around 1300 RPM's. It would chug when I gave it gas and then resume back at that 1300 rpm.
The idle is relatively rough, definitely doesn't feel normal
Then after about 3 minutes of this idling, the car cut back out and I'm back at square 1

So I think what the problem was is that the Throttle position sensor had some water in there or something. I sprayed it out with electrical cleaner and the car seemed to work just fine after a little while. kind of weird I'm going to drive the car just to make sure but it seems to be functioning normally now
