hello guys.... excuse me if maybe I'm wrong section.... I have a problem with a suzuki vitara the old model, it seems to me the year 88/89.... practically c'? the relay of the fuel pump that turns on and off constantly..... with a strong frequency....in addition, the indicator lamp mil ? on.... I can not enter diagnosis.... so I guess that is the fault of the engine control unit since ? already happened to another person.... to when you know someone who can repair them?? mounting an ecu mithsubishi silver color... I am in the area of fermo, marche.... thanks a lot
