Hello all, I have a 2002 WRX and I don't know how i could find out if my ecu is the problem. To start from the beginning, I was trying to find the output of my ECU that could turn it from automatic to manual in the hope of getting rid of p1596 error (automatic tranny diagnosis input signal high input). I made the mistake of of removing the ECU from the bolts that i now know that ground the ECU. I tried cutting one wire (which i found out that was for the knock sensor.. wrong electrical diagram) After i cut that wire, maybe 30 seconds later the car wouldn't start anymore. After re soldering the wire, i found that the fuel pump wasn't priming. After troubleshooting everything possible with the fuel pump, i replaced it thinking that was my issue. It didn't. Still wouldn't prime. I have tested all the wiring from the fuse all the way to fuel controller. All is good. I then thought to myself i will just bypass the whole line and wired 12 volt directly to the fuel pump to run it continuously to see if i could get the car started. With the pump running and car turning over, i get no start now. I assume that if the fuel pump is working now at full blast, will it drown the engine and prevent it from stopping? How do i know if i blew the ECU? thanks to anyone that can help me.
