I've been having trouble starting my Audi A3 and think that it may be due to a faulty fuel pump. How can I troubleshoot and fix this issue?
ReplyFirst, check the fuse and relay for the fuel pump. If those are in good condition, try replacing the fuel filter as it may be clogged and causing issues. If the problem persists, it's likely a faulty fuel pump that needs to be replaced.
If you have access to an OBD-II diagnostic tool, you can use it to check for any error codes related to the fuel system. This can help pinpoint the issue and save you time and money in troubleshooting.
