Well the story goes MB replaced the starter (560.00 parts) . Now it cranks but wont start ,after a few hour of diagnostics found no code but think its the AAM and or the ME boards (1500.00 parts) MB would give me the boards for 750.00 in good faith. Well they replaced the AAM only and the starter ,the truck now runs and starts fine 1600.00 later....... Thank you for your Forum to vent Matt
