How can I troubleshoot a faulty fuel pump in an Audi 80?

I've noticed my Audi 80 is having trouble starting and suspect it may be due to a faulty fuel pump. How can I confirm this and what steps should I take to fix it?

First, check the fuel pump relay and make sure it is functioning correctly. If it is, then you can test the fuel pump itself using a multimeter to check for proper voltage and amperage. If the readings are off, then the pump is likely faulty and should be replaced.

I had a similar issue with my Audi 80 and found that the fuel pump wiring harness had corroded and needed to be replaced. Inspect the wiring for any signs of damage or corrosion and replace as necessary.
