cummins cranks but wont start
 

I was driving my 01 24 valve vin6 and it just died no sputtering or anything just died on me and wont start its been about a month I have good fuel pressure good batteries good grounds a new injection pump but it still wont start it just cranks. I tried spraying ether and it tried to start a little better but still wouldn't. I could really use some help.

Start with checking your lift pump.
