i bought a vr6, which runs sweet as a nut. got it home and needed to do some welding so thought best to remove the battery. i duno whether this was needed, but i did it anyway just to be safe. now as soon as i put the negative battery line back on, the alarm/immobilizer goes off, and wont turn off via the key fob like it usually does?! pissin me off now and need help badly! any ideas?
