1989 Chevrolet R2500 Suburban Silverado 7.4L Fuel Pump
Posted to GM Electrical on 7/9/2012 20 Replies

fuel pump keeps running after engine is shut off. Disconnected fuel pump relay and oil pressure switch and the fuel pump continues to run. I then pulled the ECM fuse and it finally shut the fuel pump off. Is this a possible ECM problem?
