Check that the fuel pump is working and pumping fuel (fuse or burnt out) as it sounds like there is no fuel in the carby. To check if the engine is going to run remove the air filter from the top of the carby and pour about a table spoon of fuel directly into the carby throat. Replace the air filter and crank the engine. If is going to run it will fire and then stop
sometimes when you run out of gas you can pull up the dirt from the bottom of the tank and damage the pump one quick way to see if you have a pump or filter problem is to put gas directly into the carbuerator or throttle body if fuel injected you can try spraying starting fluid into the air intake also try heet in the fuel tank i hope one of these works for you also to make sure your fuel pump is running you can take off the gas cap have somebody turn the key to on (not start) and put your ear by the tube to hear if the pump hums or runs this primes the prior to starting I think i should be a pump.
diesel engines high pressure pumps not suppose run dry.diesel fuel keep high pressure pump cool and lubricated.problem could be fuel pressure regulator in the fuel filter water separator housing.replace fuel filter see if it helps problem could be fuel pressure regulator in fuel filter housing, the fuel pressure regulator has a air bleed orifice that allows vent to the fuel tank.make sure fuel pump fuse okay pump getting power. i would let garage or dealership check it out if all fails because your diesel engine fuel timing is pcm controlled if let fuel system go dry you probably have to have fuel injection timing reset or could have damage high pressure pump letting it run dry i hope thats not the case because high pressure pump not cheap part i hope it not that.
I think you are on the right track. It sounds like you have a fuel flow problem and those are the two items that immediately come to mind. I would start with the filter and then move on to the fuel pump if there is no change.
You are thinking right.
Try the Fuel Filter first and see if that helps or fixes it.
If not then go ahead and replace the Fuel Filter.
Most Fuel Pump Warraties require a new Fuel Filter.
The Fuel Pump failure is obvious when the engine warms-up (fuel pump is working longer). The longer the Bad Fuel Pump works the more likely it is to stop working. Waiting allows the Fuel Pump to cool down and allows it to engage again.

Well if theres power going to the relay but not out, then you need a new relay. If theres power in and out of the relay, you might need a new fuel pump. The electric fuel pumps inside the tank are actually lubricated by the fuel as it pumps it, and if it runs dry long enough, it can burn out the pump
simple : obtain replacement pump from parts provider (no used stuff)
Now help me out here: thats the year they were bolted to the pass side front of engine
and not inside the tank right? (better go look to see for sure)
using a tube wrench unscrew the fuel lines (i use large wire nuts to temp block off fuel leakage)
with a 12 mm wrench undo the two side bolts holding the pump to block
wiggle pump it should come straight off
clean mounting place on block with solvent let dry
silicone back (or use gasket that comes with pump ) of pump
apply pump to block (depending on where crank stopped you may have some tension on arm you will have to overcome to get flange to meet block )
use locktite (blue)or simmiliar thread lock on bolts retighten firmly but not hang up the dog tight
use light grease or vasolene on tube connections don't try to tighten dry
Now the fun part your diesel now has air in the fuel system
there are two ways to remove this ( hard and harder)
your choice here are both methods
loosten the fuel supply line for #8 injector ( I did not say remove) 1 full turn ought to be enough
crank engine 30 seconds only
wait 5 minutes for starter to cool down
crank engine 30 sec again
did it start but runs rough while it's still running tighten #8 injector (caution fuel under high pressure)
engine smooth out good your lucky
engine did not start yet
wait 5 minutes
crank engine 30 sec again
if so tighten #8 injector up
Now here's something I've done to my diesel to make this much less a hasstle
trace fuel line as it comes up from pump
obtain a small low pressure electric fuel pump and a two short pieces of fuel line
and a few clamps
use tube cutter and cut fuel line just before it bends to go in filter
slide tube and clamps over pipe (both sides)
insert pump observe flow arrrow towards filter
the wires of pump can be stretched over to #1 battery terminals
now any time you change a filter or open your fuel system for any reason
all you need do is connect pump to battery
open sharader valve on top of filter for a few min
and start truck as normal
then disconnect wires and stow away for another day
