Hello people, I`m new on this forum congratulations on the great work. Here`s the deal. My car got crashed by a guy, no big problem. When I took it to a shop the morron (sorry) of "mechanic" unplugged the battery and the plugged another one with the car running. The car stopped and never started again. There is no electricity on the injectors and the distributor went wrong. I changed the distributor but it gets very little current. The computer has some lights for fault codes but the slightly flash. I`ve heard somewhere that this cr has like a "switch" that stops all the electric system when something bad flahes but I don`t know where it is. Another thing is that "security" keeps on flashing on my digital dashboard, I`m kinda pissed off with this guy but I want my car back. What can i do? thanx a lot
