FiTech EFI system

I've had the FiTech and FCC on my 440 Coronet now for about two months and unfortunately I have not had success with it. The unit will not reliably start; stranded me again today; first two starts were fine.
Original problem was hot start; turned the idle screw to lower the warm idle IAC to < 10; decreased the FCC PWM to 40. Increased the Crank fuel. Had to do a system reset a couple weeks ago. The prime shot turns on, engine wants to run for about 1 - 2 seconds, then no fuel. I talk to FiTech every week - I know Cody by voice at this point. Very frustrating. Only put 400 miles on in 2 months because I don't trust it.
Well, it's been a couple of hours, going to drive back to the parking lot and see if the car will start. Guess I'll call Cody again tomorrow....
