I have a 2008 Audi A6 3.2l v6 and my engine will crank but won’t start, I believe that the problem is the fuel pump relay, I have ordered the part from FCP but I just don’t know where the relay is located in the car. I have found all of the fuse boxes just not sure wich fuse it is, does anybody know which one it is?

That's for the 2.4L. Check this: https://www.audiworld.com/forums/a6-...ation-3044876/

The 3.2 does not have a fuel pump relay. Scan your engine for fault codes. It will let you know what's wrong.

There is a solid state fuel pump control module underneath the fuel pump access cover under the back seat. This takes a signal from the ECU to modulate the fuel pump based on load. If the fuel pump isn't running, check that. You can bypass it and send 12 volts directly to the fuel pump to test it.
