My wife's 740 wagon stalled while driving last Tuesday, and she had to get the car towed home. Hasn't started since. From some simple checks, I believe that it is in fuel delivery. I tried using the onboard diagnostics, with the pin in socket 2 to test fuel system, and got no response -- light doesn't flash at all. The light does come on when I first push the button down to start the test, though. For ignition fault test with pin in socket 6, I get 1-1-1 indicating no detected fault. So, the system seems to be working. Does anyone know what a "no response" means? Is that diagnostic in its own right, without flashing a code?
