First, what yr is your truck?
WTS Light? - do you get it when you first roll-on the key?
Tach Movement? - does the tach needle move up slightly when cranking? (this is where your yr would help, in '01 there was a change to trucks who's instrument cluster contain a Trans Temp Gauge, they aren't supposed to show cranking rpm)
Fuel - pump runs? Fuel refilling filter housing? Tank below 1/4?
Is it cranking fast enough? - it won't even TRY to start if cranking really slowly.
Is your truck "chipped"? If so, remove it as a Test.
Has the "Check Engine" been coming on at all? - codes would be the fastest way to direct you. Unfortunately, it takes a special scanner to retrieve them...
