Does my 84 SD have such a relay? I drove my 83 SD with a pretty dead battery and no charging system, and the car didn't die. My former 91 Volvo 940 wagon wouldn't run at idle with a dead battery, so it must have had an electric fuel pump also. I've read that the M617 engines can run with no electrical system... wondering if this is true.
