I had the engine rebuilt and in doing so found the stock turbos were totally useless (cracks everywhere) replaced the turbo with a GT32 from garrett and built a manifold for it. Since the stock ecu and the single turbos don't get along I installed the PFC. But the car wont start, it will "catch" from time to time but wont make it past about 500 rpms. I've been pulling the spark plugs after 3-4 attempts just to make sure it doesn't flood and have also checked to make sure the coils are strong and they are. I tried the stock ecu and got nothing, not even a "catch." Tryed some starter fluid...no help. I can smell fuel and have removed the UIM and watched the injectors spray.

The only thing that may help diagnose the problem is that while cranking the tach will flicker up and down a few times but not in a pattern and looks to be random. So maybe bad CAS but i checked the wiring and it's okay and the PFC sees an rpm in the monitor screen.

you can't see the primaries spray by just removing the upper manifold. if your secondaries are spraying when you're cranking it, that could definately cause it to flood out.

good point, I could see fuel vapor and assumed it was the primaries but I should check to make sure. thanks

You need to recheck all of your connections; wires and hoses.

It is posible to switch primary injector connectors, and crank angle sensor connectors.

maybe try putting the stock ecu back on try starting it, and then check for codes.
