Engine won't start with new tune.

[EricDM]

Need some help please. I have a 57 Bel Air with a LS3/4L60E conversion. The attached tune Old.hpt was in the car and ran fine. Problem with it was mismatched trans OS. I copied engine data from the Old tune to New.hpt tune, also attached, and did write entire and now engine won't start. This is my first attempt at engine tuning. I have read everything I can find and at this point I don't have a clue. Thanks for reading.

you need to disable

1632 (theft)
and startcheck disable

and write entire also connect scanner and see if you have DTC

i didnt look at the tunes but my quick guess

[EricDM]

1632 was disabled. I disabled the starter check. No codes reported. Still won't start. Any help is appreciated.

does it stumble and then die? Do you hear the fuel pump come on for 2 sec before cranking?

Your "Starter Fault Checks" are still "Enabled" in the "OS" tab. Try disabling that.
