How to troubleshoot engine starting problems in an Audi 80?

I have been having issues with starting my Audi 80 lately. It takes multiple attempts to start the engine and sometimes it doesn't start at all. I have checked the battery and fuel pump, but they seem to be fine. What could be causing this issue?

One possible cause could be a faulty starter motor. This can lead to difficulty starting the engine. I would recommend getting it checked by a mechanic.

Another common issue could be a clogged fuel filter. If it hasn't been replaced in a while, it could be obstructing fuel flow to the engine and causing starting problems. It is a relatively simple fix that you can do yourself.
