so i have a bully dog single pos. chip i guess? i dont know it came with the truck but doesnt have a position selector or anywhere to plug it in to the chip...anyway, i pluged in the pcu and now it wont start. will turn over just fine, but wont start. i then took it out and it started just fine. i continued to fiddle around with it like that, but now it wont start with chip out either. any ideas?
