Did you check the correct relay? AMG harness is different from non-AMG harness. Search and ye shall find...

That's for the non-AMG car. AMGs use a different wiring harness.

The 2003 through 2005 has one fuel pump relay on the passenger side behind the panel (no access port so you have to pull the whole panel). 2006 has two fuel pump relays on the passenger side trunk.

Here's some info on the differences between the two versions:

Read the links in this post (entire threads because some info does not come out until the last few posts):

If the tank warranty work was performed and the dealer failed to install the fuel pump adapter cable, you may have a valid claim against them.

Fuel 40 amp. I assume air pump relay is 40 amp but they never seem to burn out. Part numbers are out there. Advanced search on my username and keywords such as fuel pump relay or fuel pumps.
