370 ls, 85 lbs injectors, ls6 intake, ported 862 heads, gt-88 turbo, TH400 94 trans am.

I bought this motor complete from the injectors down to the oil pan, had the same tune put into my computer as the previous owner, my computer and harness are out of an 02 6.0 truck. his was a 99 ls1 camaro harness and computer.

the car turns over and starts but dies with in a few seconds, Ive got fire, but all the plugs are wet with fuel, it stalls out like its dumping to much fuel in at once, Ive adjusted the fuel regulator down and it does the same thing, could this have something to do with the truck harness not being the same as ls1.

No rear 02s, vats, trans, maf. (pcm has red and blue plugs just like ls1)

did all the sensors and connectors plug in? i wouldnt think so since one is fbody and one is truck.

Only difference in the harnesses would have been the MAF connector. Everything else should have plugged in. You didnt swap the MAP and CAM connectors by mistake did you? Are you sure you have the right injectors programmed into the PCM?

double checked the cam and map sensor, they didnt get mixed up. Same tune on the exact same injectors

Had the same thing happen to me. My exhaust terminated just after the O2 sensors and air reversion led the sensors to believe the mixture was too lean resulting in excessive fuel delivery. Added tailpipes...problem solved

I have reverse truck manifold set up, I put the 02s right after the manifolds, goes through the turbo and out a 4 inch down pipe, comes out at the front bumper, others have ran it like this so I dont think thats the issue
