Issues starting car after tune

All,
Just received my ECU’s after a tune. After securing all connections, I’m having issues starting the car. The car will start and run for a few seconds before cutting off. I’ve checked and rechecked the connections thrice. Anyone had similar issues before? This is my first experience with a tune so, I’m sure I’m screwing something up.

John

Hopefully they sent you the right DMEs and not someone else’s… could be a coding error too.
