First, what yr is your truck? (some show cranking on the tach, some don't)
Next, here's my No Start checklist.
WTS Light? - do you get it when you first roll-on the key?
Tach Movement? - does the tach needle move up slightly when cranking?
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.
(I know you've answered some of that already,,,)
Also, it sounds like you're not using the right kind of scanner, our trucks are NOT strictly OBD-II and those scanner won't work well. You need a professional scanner to know what the problem is. Most everyone here like the AutoEnginuity for personal use, otherwise find a Snap-On, MAC, or Ford scanner to help you.
