Got my scan tool up and running and it reported a single P2071 code whether I set the scan to Chrysler Enhanced Powertrain or Mercedes SL or SLK.
Found this one reference to that code -

I just got done inspecting the RCM and did find another thing to look out for. If you've removed/replaced the fuses, check the underside of the module insert when you remove it. You may see the connectors to the fuses have actually pused away from the top. I pushed them back into place and could feel them slide on to the fuses. While I was in there, I also tried to clean the relay contacts with some contact cleaner. I also sprayed the connectors and the plugs then used compressed air to dry everyhting.
Interestig to me is the pattern is now 1 no start, 2 crank no run, infinity no start... Also been interesting to note that the default mode for the radio is ON after every time I remove/restore power!!!!
Any thoughts? Anyone know which relay is the fuel pump?
UPDATE, started the tests on PG 498 of the 2004 Service Manual and failed at step 2, no voltage on pin 3, repair fused engine relay control. All fuses good (tested continuity), all solder joints look good, ...
OH THE PAIN!
