Are you getting smoke out your stacks when you crank it over?

Do you mean you cranked it over and the bowl never filled up ? or do you mean you just turned the key to the on position?

These trucks have mechanical pumps not electric so if you just turned the key that would not work.

on the other hand if you cranked it over and checked the fuel filter cont. and there was no fuel then maybe it could be the pump

Check Fuses.
The fuel heater is off of fuse #22 (30a). It also powers the PCM.
If blown unplug the heater.

Checked oil level?
Check HPOP res level?
Did you remove/check the chip?
Tach moves?
If above is good you have to check ign switch then HPOP system.
Easy way to check the switch is to leave it in the run possition then go under the hood to jump the starter relay. If starts its the switch.

Has the truck been taking longer to startup lately?
There is a good chance after it cools down it will start. (cold soak)

Be shure with the fuel. It does not take much fuel for it to try and start.

bill seems to have this one covered pretty well so far, i agree the algae wont cause the problem you have at this point, it ran fine before you shut it down, algae would be more of a wot problem right now. concentrate on the basics for now.

Fuel is to low. Maybe from you draining it? Fill the can or check it after you have cranked it some.
If you look at the standpipe you will see a hole (valve) in the side of it.
When you install the filter it pushes down on the top of the standpipe.
It opens that valve. This valve allows fuel to flow.
