How to troubleshoot engine starting issues on an Audi 80?

I own an Audi 80 and I'm having trouble starting the engine. The battery seems fine and all the lights are working, but the engine won't turn over. What could be causing this issue and how can I fix it?

Hi Julia, this type of problem can be caused by a few different things. It could be a problem with the starter motor, the ignition switch, or even a faulty fuel pump. However, the most common culprit is usually a weak or failing battery. I suggest checking the battery connections and making sure they are clean and tight. If that doesn't solve the issue, I recommend having the starter motor and ignition switch checked by a mechanic.
