1995 LT1 swap Will not start!! Help! help!! Help!!!I am in the final stages of my 1984 Porsche 944 LT1 swap. The motor consists of a 35,000 mile 1995 LT1 taken from a camaro. A hot cam kit installed, 75 shot wet N20 system, Custom ECM reflash removing all transmission aspects (I use the porsche transaxle), removed EGR system, removed VATS control, retarded timing 3 degrees at WOT for the N20, brand new optispark. My problem is I cant get the injectors to run properly. The engine has never run yet by its self. The only way I can get the car to fire is if I pour a little fuel into the PCV tube it starts and runs off that little bit of fuel added. Obviously, I have great spark and at the right time so I assume the optispark is good. 1st question: Does my crank sensor in the optispark control the injectors. What I do know is I am showing no trouble codes. I did a dwell test on the injectors during cranking and they read 450 miliseconds????? I thought it should be around 10 ms. I also tried the processor out on another LT1 and it ran the car fine. I am confused that that processor is telling the injectors to fire at 450ms. Any ideas? How do I check to see if the crank sensor in the optispark is wroking properly?
I cant answer you problems but these guys can. Call 918-446-3019
John at FastChip should know the answer or be able to direct you to some one that might.....You might even get to talk to Ed Wright....but highly unlikely

Update: Since the motor was in storage for soo long six of the injectors had locked up. Funny thing is number one injector was one of the injectors still operating and that was the injector I was checking duty cycle on. I sent two sets of Injectors to New Era Performance to get cleaned and flow checked. Hopefully I can get a good set of 8....
