L92 build, No Start, Getting Spark but no injector pulse?!?
Car is an original LS6 car. Then went to a LS2 402, now new engine is a 414 L92.
Car ran before tear down. Only think suspect is a hacked up Cam extension harness. Previous shop extended the wires instead of buying an extension harness. Not sure if the wiring is correct or not.
Weird part is that the car has good spark, but no injector pulse. HOWEVER, if you use some starting fluid the car will fire up and THEN the injectors will start firing?!?
I'm puzzled here.
Any help is appreciated. I would also like to see a good diagram or how to wire from an LS1 cam position to LS2 CPS. Color codes and pin outs if any one has it...
Thanks.

LS2 Cam Sesor:
pin A = orange wire to C2 44 of PCM 12 volt reference
pin B = pink/black to C2 15 of PCM low reference
pin C = brown/white to C2 26 of PCM CMP sensor signal
LS1Cam Sensor:
pin A = brown/white to C1 73 of PCM CMP sensor signal
pin B = pink/black to C1 61 of PCM low reference
pin C = red to C2 39 of PCM CMP sensor signal
What is your fuel pressure?
