How can I fix the intermittent engine starting issue in my Audi 80?

I have been experiencing issues with my Audi 80 where the engine will sporadically not start. The battery and starter have been checked and do not seem to be the problem. What else could be causing this issue?

The most common cause of an intermittent starting issue in the Audi 80 is a faulty ignition switch. This can lead to the engine not receiving enough power to start. Try having the ignition switch tested and replaced if necessary.

Another potential cause of this issue could be a faulty fuel pump. If the pump is not providing enough fuel to the engine, it may struggle to start. Have a mechanic check the fuel pump and replace it if needed.
