B18c1 swapped in a 99ek running neptune. Everything was running perfect before I just did a custom turbo on it. I upgraded a few things in the process and now the car will not start. It does turn over and I have fuel to the fuel rail.

I first wired in the 10 ohm 10watt resistors and it did not turn over so I pulled on the wires and broke one loose so I decided to try to wire in the reistor box. Then I noticed it was throwing a new code of injector wiring error or something along those lines.

What I have done new..

Throttle body and dialed in the old TPS to it perfectly
OMNI 4 bar which I updated in neptune
PTE 780's which the offsets are not in neptune so I had to insert my own based on what they sent me. Its not exact and I did try their other offsets with no success.
Throttle body spacer

Everything else turbo related that should have no effect.. i.e.. turbo, piping, bov, etc.

Please help thanks!!

I don't have any real suggestions, but I did have a similar issue once. Even though the GM 3bar MAP i bought was brand new, it was giving faulty readings to the ECU and for that reason, the car wouldnt start. I put the map, injectors and ecu back to stock, brought it to the dyno, re-installed the map sensor and with their read-out, they were able to pinpiont the problem. Without that, I would have been stumped. Something to think about...
