So on Saturday truck was idling when warming up weird low rpm to regular rpm. It had a few times where it didn't start right Away but once I got it going on the road it was working fine. It has a fass pump that was put on 2-3 years ago. Haven't checked the pressure of it or changed fuel filter since I owned it(2years)
Saturday night I parked it now it will turn over just clearly not getting any fuel at all I can hear lift pump come on just not starting! Give me som suggestions on what may be the problem!

 

Does the lift pump sound normal?
If you have a leak in the suction line you could be pulling air in and that would prevent it from starting.

 

The lift pump making noise and running does not necessarily eliminate the lift pump as a possible problem.

 

Check the fuel pump relay?

 

How is it clearly not getting any fuel?

I'd scan it and see what codes relating to the vp come up.....after all the simple stuff, like ensuring there is fuel in the tank, the filter is clear, the batteries are fully charged....
