looks like fuel pressure problems, i've had my share of those...

could be a lot of things... OFV, pump itself, a clog... draw straw... check your fuel system for leaks...

i drove probly 10 miles with the fuel light on do you think it has anything to do with it? i dont think it ran out of fuel i shut it off and added more before i tryed to start it, also its about 35 degrees if that makes a difference

mine can be rough in the cold... i have to keep it at 1200rpm for a few seconds before i can let off... but my truck has advanced timing so i'm not sure if that goes for your truck too...

maybe your toaster is shut...

I cant even get it to start with my foot on the gas anymore... i think im gonna check for leaks tomorrow it sounds like its gonna be a fuel problem. Im wondering if the fuel filter could be clogged since i let the fuel run so low

now it wont even start when i crank it blows white smoke and alittle black. i think my fuel shut off solenoid is bad cause i have to pull it up when i turn the key to run. i put it up manually and the truck still now start...

you never really want to let a diesel get under 1/4 tank probally just sucked some trash up in the pump.

did you prime the filter with fuel correct me if im wrong but white smoke is usally unburnt fuel in your case or a blown turbo but would still start it if was turbo
