Well before I got the truck they where all left for a while with injector line off. The motor will start with a little started fluid so I don't no if it would be compression.

Crack the lines at the injectors and see if fuel comes out the line when you crank it.

ive done everything i can think of the timing is set and there is fuel going to the lines, but it will not start with out starter fuild and then wont keep running. my return line is ran to a jug for now and fills up really fast when im trying to start it so im thinking its the injectors, but i dont know how to check them.

you can take the injectors to an injector shop and have them test them or you can take them out and put them back on the lines and turn the motor over and see if fuel comes out but put do this one at a time and put a piece of paper a couple od inches under the injector tip the fuel should spray a star patern on the paper if it dosent or no fuel comes out the injectors are bad
