HELP ASAP lsj wont start after using scanner

ok so i pluged pro in used the scanner and wanted to change what gauges were show in hp and i cleared 2 codes now the car wont start first off as soon as i did clear codes then i tried to turned the key and nothing happen car wouldnt even turn over would then unpluged hp still nothing let it sit for a few mins finally the car will crank over but not fire now the car was running 10 mins before i pluged hp in can some one please help me i even tried reload the factory tune i have saved still nothing jus keeps cranking

Had that happen to a buddy of mine. They had to pop the clutch. Then it started fine after that. But as soon as he used HPT it would do the same thing.

EDIT: didnt see the part where it keeps cranking. Check for spark and fuel first.

When you re-wrote the tune did you perform a "write entire" of just a normal re-flash?

And what 2 codes did you have?
