99 dodge ram 2500 crank no start NEED HELP!!!

[99Dodgeram2500]

NEED HELP, i have a 1999 dodge ram 2500 24valve Cummins, every morning and after work the truck will start, i drive it for 15-20 min till it nice and hot, i park and shut off the truck, i wait about an hour to hour and a half and go to start the truck up again it will crank over but wont fire up, when its running it runs perfect no spitting or spuddering or dieing none of that. i already replaced the lift pump on the truck because it was weak, only codes i get once in a blue moon is the the crank sensor and there's no other codes.
Im getting power to the injection pump (injection pump was changed when i bought the truck two months ago),and after cranking i can hear the lift pump running for 20-25sec as expected as normal operation.

any suggestions on my problem will be greatly appreciated and thank you

Do you eventually get it running? Auto or manual?

Did you replace the crank sensor?

My 02 was doing the same thing had to rewire the lift pump on a different circuit. Some sort of short on the stock circuit and it was easier to move it than fix the short. Wires down there are in a bad place. Crank sensor will keep it from starting also.

Just because the lift pump is running, doesn't mean you're getting fuel. When's the last time you put a fuel filter in it?

Also don't rule out the possibility of having some junk in the tank. Check the screen on the lift pump if it comes out any way other than clean you may need to drop the tank and clean it.
