Hello folks,
I have an e70 4.8i with
crank, no start.
My findings/tests so far:
- Tested the fuel pump motor successfully with BimmerGeeks ProTool. But it does not "click" or activate when I prime the car - I don't hear the humming/buzz.
- Checked many fuses/relays, found nothing faulty.
- Cleared a crankshaft position sensor fault by replacing the sensor (was really hoping this was the issue)
- Replaced battery (and registered).
- Compression test in one cyl to rule out timing - good result.
A few things to note that I have noticed with the car:
- No spark when cranking.
- The old crankshaft position sensor was not the expected part number and was connected with a modified connector. I have ripped the modified connection and connected with the original connector. This seems weird to, I have no idea why this was done.
- There are various weird electronics behavior.. Seats don't move. The iDrive system is acting weird, FM/AM is not selectable. The unlock/lock beep is intermittent. Likely more that I have missed.
