Car doesnt start, strange sounds observed...
1991 735. I was driving down the road when car just stalled on me. Dash lit up like a X-tree and I pulled up on a side of the road.. While trying to restart it, i didnt` recognize the sound.. Usually, when you crank the engine its has that low, pumping suhr-suhr-suhr-suhr wrooomm! sound.... This time, its juts monotonous - high piched whining sound of a starter
motor..... Doent even grab.... I have been driving on almost empty for a while I blamed dead fuel pump (no sound when ignition key is turned, that familiar "Pzzzzzt" for 2-3 seconds).
Changed fuel pump.
Car doesnt start till. Still makes the same high pitched sound when i crank the engine, what a heck could it be? I am confused,
