So I swapped in a S5 Turbo II engine into my 89 GXL. This engine has an OMP delete so when I got my ECU I sent it to Rtek and installed a 1.5 OMP delete. Everything is done, and I can start it up. But it won't stay running! I'm at a loss right now. There is fuel pressure and spark. So this guy I know has it right now. He's saying that its probably one of two things. Either its losing the injection pulse to the injectors after it starts up, or the ignition is out. I juts wanted to get your guys' opinion. Anything you think it might be, that I can check would be helpful. I want my car back, I'm riding my bicycle to and from work and just going crazy. Thanks

If you need to know anything else just ask, I'll try to give you as much info as I can.

large vacuum leak.

I wish it was that simple. Next thing I'm about to try is plugging the n/a ecu back in to see if Rtek messed up the one they sent me. Even tho they "test" all their ecu's before they send em back. Anybody ever have any issues thru Rtek? Just waitin for my throttle cable and bracket to get here before I even test the ecu tho. It's in the shop on the other side of town...

I'm not sure that an FC would be my first choice as a daily driver, let alone my sole means of gas powered transportation.

Is the ecu that you have an N374 or N370?

Why not, it's just a car.

What if it is? Did you check? It's totally possible that it could be. When you start the car, does it rev up to about 3.5k and die right after? Either that or the MAF is not plugged in. It will cause the same symptoms, and it's gotten me a few times.

Tyler [S5 FC]

Yeah, there's no leak. It won't even make it to 1k, I can here it firing but it won't rev or idle. I've meaning to check the maf but haven't gotten to it yet. Altho it was running for 3 days (in safe mode before I went rtek) Then in between going rtek my friend put in the TII wiring harness as supposed to the n/a one. Then no luck since that point.

Bought a 94 accord knowing the plans for this car, so no more riding a bike (which I only had to do for 4 days)

theres your problem. you switched over to the turbo harness. there is something you have to do to make that work. but i dont know what that happens to be. has soemthing to do with how it hooks to the other harness

switch it back to the na one

Tyler [S5 FC]

The n/a one is no longer. What do I need to change? Please explain more, can I fix it with what I have, do I need to buy another n/a harness?
