Default TRUCK WONT START

Hey guy I have a 92 dodge W-250 with 167,000, I haven't had any problems with the truck until today..here's my problem last night I was driving on a dirt road for about 20 miles, the road was a little rough but nothing to bad for a truck like this..anyways when I went to start the truck this morning it didn't turn on all I get is a crank but won't fire up..does anyone know what could of happen?

Hot wire for the fuel shut off solenoid could have wiggled loose. Look at the back of your pump directly below the fuel return line. Dark blue wire i believe.

Thanks for the help, I went out and checked it and there were no lose wires....I pumped the manual lift pump for about 3minutes or so and it fired right up...could this be going out? Totally threw me for a loop...

Your injection pump should pull through the lift pump if it went bad, not good for your injection pump but it should start, I would guess you have a fuel leak somewhere and got air in the system.

Either this^^^, or you jiggled a bunch of bad stuff around in the bottom of your fuel tank and some of it plugged in the line. Drop your fuel filter and drain it in to a clear vessel and have a look if there's any floaty's.

Thanks again guys...I drained fuel filter and diesel was clean, I then bleed the fuel line and now I haven't had any problems with it all day...truck seems to fire up better then before..whatever it was seems to be gone for now, hope it stays that way
