On a 99 do they have a ignition coil and crank positioning sensor? that is where i would look next, then if it still wont start after replacing that, only 2 things i can think of, either it jumped time or bad ECM. I take it you have already made sure you have fuel to the injectors? And have you had someone with a OBDII scan tool come over to see if you have any codes in the computer. That may direct you in the right direction

how do you know if it won,t crank.i think you mean your truck won,t start don,t you? it might not be fuel, it might be spark. check the spark at the plugs. if no spark then it could be the coil or module.
check the fuel pressure , i have had pumps work but not have the right amount of pressure
