What year is the car?
1/ Did you get the pump(s) programmed to the car for the PATS system?
2/ Is the E.M. light flashing when you spin the engine with the starter? If so there's a problem with the immobiliser/PATS system.
3/ Is the interior light staying on?
4/ What error codes did the electricians get from the on-board diagnostics?
5/ Did you have any of the 'faulty' pumps tested?
