trying to help out a friend car had a no crank issue they had the starter off and half torn apart before i got there went ahead and swapped out the starter for new one. car started ran for about 30 seconds and died, now have no power anywhere in the car except the check engine light comes on when the key is in the run position. I'm thing maybe the ignition switch died, but wasn't sure if there was some kind of anti theft relearn I had to do if the battery was disconnected
thanks
Dave
