I know this is in the wrong forum, but there's so few of us, nobody goes in the other ones, also I know it's a long read but i really need some help.
00 civic ex, was turbo'd, now returned to stock (need to pass emissions)
2 nights ago, eveything was fine. I'm back to the stock ecu and everythng. The next morning i went out to start my car and i could hear a bunch of relays clicking and the car wouldn't start. With the key in the run position, only the seatbelt light and the brake light would illuminate on the dash. When i tried to start it i could hear the fan come on, and nothing would happen. The battery voltage is at 12 volts.
So i push it in the garage, checked EVERY fuse, and they're all good. I took out my turbo timer, and my VAFC (since i don't need either of them really), and double checked all the wiring involving the ECU and the Ignition, everything is good. Then i followed the service manual test procedure to test the ignition switch, and it's working fine. I then decided to test the PGM FI relay as per the service manual. That too is fine. I then tested the wiring harness going to the PGM FI relay, and that's fine as well.
I also tried hooking up my P28 to it (to make sure the ECU wasn't cooked) and I got the same results. However one time i bent the wires really hard and it was normal! So i thought the problem was solved, i go to start it, and the lights on the dash went out again, and the relays clicked, and then the light slowly lit a little. So i'm assuming there's a lose connection somewhere. The only other thing i have found that is wrong is on the middle connector for the ECU there's 2 brn/blk wires and they're both grounds for the ecu. One of them has continuity and the other does not.
I cleaned the engine and chasis grounds, and i even found the grounding point for those two wires, and cleaned that too, and i can't get continuity on that ground wire. I visually inspected the harness and i can't see anything that could have pinched or severed it. So i'm kind of clueless in that respect. But my only hypothesis right now, is that not all the wires in the ECU are connecting/getting ground. All the others have ground and power.
It just pisses me off that one day, it doesn't want to run when it's perfectly fine. Especially since i haven't fucked with anything in weeks. Complete bullshit, but if any of you guys have ideas of other things to test of look for, that'd be awesome. I don't know what i'm going to do if i can't figure it out since it's my daily driver and i need to get to school
help!!
