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!!

 

No clue anyone?

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...

 

Will check thanks. Anyone else want to chime in please do so thanks.
