wondering if anyone has any ideas. heater matrix was leaking it dripped onto the ecu shorted it out and injectors 2 and 4 were pulsing constantly filling the bores with fuel. i checked there was a spark, fuel obviously coming up, (checked 1 and 3 aswell) replaced ecu tried to start car but it will only wind over fast. thought chain had snapped but cams are turning so guessed it was o.k. anyone any ideas whats wrong or what could be wrong? thanks steven.
