5.9 Magnum help needed

So I tinkered with the ram for about an hour or so yesterday. I checked to make sure all the sensors were still plugged in/connected which they were. I also the basics oil,coolant,etc just because its been awhile. I also had a friend attempt to start the truck while I laid underneth with my ear to the tank. It chocked and almost started but no cigar. I also did not hear the fuel pump prime so im going to go ahead and replace the pump and filter. Someone mentioned that it was easier to remove the bed instead of the tank is that really true? I have a motorcycle jack so I could use that to guide the tank down when I unbolt the straps. what do you guys think? bed or tank?
