I have been experiencing issues with my BMW where the fuel pump seems to be malfunctioning. What steps can I take to diagnose and fix this issue?
ReplyFirstly, check the fuel pump relay and fuse to ensure they are not the root cause of the issue. If they seem to be functioning properly, the next step would be to use a fuel pressure gauge to test the pump's pressure and volume.
If the fuel pressure and volume seem to be within the recommended range, the issue could be with the fuel pump itself. In this case, it would be advisable to replace the fuel pump to resolve the issue.
Another potential cause of a faulty fuel pump could be a clogged fuel filter. It is recommended to replace the fuel filter every 30,000 miles to prevent such issues.
