Car wont crank after chip install

[/Alessandro\]

Hey guys, so I installed a TMS chip the other day (notch to notch, it was not in backwards) and when I went to start the car it would crank but wouldnt turn over, I heard of some people having to crank their cars a bit after chip installs so I cranked it a few times and nothing. So I thought no big deal probably a bad chip put the stock one back in crank the car sounded like it wanted to turn over then I heard a bang from the engine and now she doesnt crank anymore.

Anybody have any idea? I spoke to Rocco we we're thinking the plugs could be soaked with fuel so I took them out, dirty but no fuel on them. So we're thinking fried ecu. Anybody ever witness something like this before?
