had the same problem and I did the same first three items you mentioned. At the time the Cummins Tech indicated that if those items did not resolve problem, then the next item to look at was the PC control board which of course controls the operation of the fuel pump.
Those first three items cost me approx. $600 including labor. For your info the control board is approx. $348 plus labor.
Wish you luck.
Food for thought
Ran the generator for the air conditioner as I drove this weekend to ND. ran both the genny and the ford air at the same time. Big mistake. After approx. an hour battery trouble light started to glow. READ the manual and it specifically states that not to run both at same time. Turned off the genny controlled and had no further problems.
