Did the vehicle have crank with no start? My fuel pump control module went out while driving on the freeway, came out of nowhere with no warning. When I tried to restart the truck on the side of the road, it'd crank like normal and sounded like the motor was turning via the starter just fine, but it never fired up. As mentioned, it ended up being a faulty fuel pump control module so the motor was not receiving fuel. Dealer told me if it was the crank bearing (it's the 6.2) or lifters it would not have sounded normal while cranking, or might even be seized up completely and unable to turn via the starter. They only had the truck for a day and it's been running fine with a new FPCM since then (that was last week, fingers crossed).
