Fuel pump running when ingnition ON, 280 SL
280 SL W107.042 US model from 1982
The fuel pump is running when the ignition is tuned ON, and obviously when the engine is running.
As per Chilton's guide, this could come from a defective safety switch, or from a stuck pump relay. Am I correct?
Should I repair it or leave it as it is?
Many thanks from your help
Leave it alone. The fuel pump is suppose to run and prime up when the key is in the on position.
Thanks for the quick reply. Just read the Chilton's saying "the pump will only run if the starter motor is actuated or if the engine is running" Thus my question.
