So your injectors are not firing properly? It sounds like you've disconnected your fuel rail and tried to start it to see if the injectors shoot fuel, is that correct?


It sounds like you've spent quite a bit of money already on this. Do yourself a favor and buy a in line fuel pressure gauge. It will at least let you know what's going on with that. Do you have an adjustable fuel pressure regulator? The Nismo/whatever other one looks like the Nismo FPRs are garbage and I've heard they shit out and are not consistent.

Do you have any way to try out some new injectors? The injectors could be shot for whatever reason.
