HELP PLEASE

 

It would have been best to have left this reply in the other thread that you already started, as you will just get more questions and the same responses you got in the other thread. this makes it hard for us to help you if the answers/questions are split between two threads!
so have you added fuel to the tank?

after adding fuel (fuel tanks are well known to be empty even if the gauge reads 1/4!!!)
loosen the feed line to the VP, that would be the fitting that looks like tire valve, I think its a 19mm or 3/4 then bump the starter to activate the LP, when you have a solid stream of fuel at the VP, tighten the fitting back up, then loosen off as many injectors as you can reach, and crank the engine over, the engine may try to fire if it does stop cranking and tighten up the injector lines, and try to start the truck again. it should fire up and run, might be rough for a second or two.

if you notice that only one injector seems to be showing fuel and the others are dry, thats pretty much a definite sign that you would need a new VP.
