I hope someone can help me here. I finally got my car to turn over, but it does not want to keep idle. I have checked every sensor, every hose, fuel, everything. I have spark since i tested it with my volt meter. Any suggestions to why my car cannot keep idle? Also, the car has no turbo yet, I am running a stock tune on new parts. (i.e. 8.8:1 compression and 1000cc injectors. Stock cams and throttle body and intake manifold.)
I also noticed when taking the spark plugs out, that the plugs in cylinders 1 and 2 were completely clean, and 3 and 4 were black like misfired fuel. Any suggestions on that? I will be performing a fuel pressure test tomorrow morning as well and will post results.

Still need to answer the question about engine management. As mentioned above big ass injectors do not work on a factory tune. Also, it is why I asked your fuel pressure. Since you said you are going to perform a test, safe to assume you have never set it, and that means you are likely on a stock FPR. You can see where we are going with this....

I have also done a fuel pressure test and i have absolutely no fuel pressure. Also I will be switching to the stock injectors as well because as you all mentioned, the big injectors I have will not run correctly with the stock tune. In the near future I will be installing MS2 to compensate for the 1000cc injectors, as well as install my turbo and intercooler systems.
