How to Troubleshoot Intermittent Starting Issues in Audi 80?

I have been having problems starting my Audi 80 lately. Sometimes it starts without any issues, while other times it won't start at all. I have checked the battery and the starter, and they seem to be working fine. What could be causing this issue and how can I troubleshoot it?

One possible reason for intermittent starting issues in Audi 80 could be a faulty ignition switch. It is responsible for sending the start signal to the starter and if it is malfunctioning, it could lead to starting problems. To troubleshoot this, you can try turning the key to different positions and see if the car starts.

Another common issue that can cause intermittent starting problems in Audi 80 is a dirty or faulty fuel pump. The pump is responsible for delivering fuel to the engine and if it is not functioning properly, the car may not start. Try cleaning the fuel pump or getting it checked by a mechanic to fix this issue.
