after my hea dinstall when i went to start the car it just turned over so i unplugged the box and it fired right up. i sent the box to msd to have it checked over thinking something may have broke internally. recently i just purchased the same box and it does the same thing. i kno its not wired up wrong cause i got the msd plug up kit where u just plug the colored wires together and hook up the + and - could my igniton module cause this? whats wrong?

 

I'd say check the ground and the power wire to the box.

 

well i went over everything and i found out that on the msd plug up kit the center pin terminal had slipped out of its housing so i opushed it back in until it snapped into place plugged it up and it is running good now, thanx
