tuning issue with aftermarket efi

[Grumpy]

Throttle position sensor

Have a strange problem. I have a Accel DFI Gen 7.
When starting the engine, it starts then dies quickly.
There is no movement on the Accel dash board for the TPS. When I move the throttle by hand, it response smoothly. I performed a TPS calibration, same problem. Thanks for your assistance.

Id be looking at the IAC and all the electrical connections to both the TPS and IAC it seems obvious one or both are either not correctly connected or out of adjustment. some of the info in these links will apply some won,t
