[QUOTE="bmwky, post: 84262, member: 102"] No. the fuel pump will only run for a few seconds when the ignition is first turned on (i.e. started) the fuel pump will run constantly only if the fuel pump relay receives a signal from: 1) motronic ECU in a six potter or 2) rpm signal from the ignition system of a 4 potter L-jet you may have a faulty relay.
