long story but alarm on car is a crap fox guard or something anyways the fob has broke and no longer opnes the door with the remote locking or diabsles the aftermarket imobiliser. after a few swear words and cutting stripping and rejoining wires the imobiliser is now disarmed in away that the car cranks over but wont start like its got the fuel cut is this maybe a secondary imobiliser? or has it been wired the the fuel pump?
