It may have been unplugged and jumped, that seems to be fairly common. The switch have been known to trip somewhat randomly or have otherwise proved themselves unreliable.

on your fuel rail, there is a shraider valve (looks just like a tire valve). uncap it and poke the little button in the middle. be prepaired for fuel to spurt out onto your fingers.

pull the fuel pump fuse then start up truck run it dry of fuel and youll have to cycle the key a buch to get fuel back into the system to restart .
goodluck

i didn't get a chance to change it tonight well the reason im doing all this is because i have a miss and i can't find it i pulled one plug wire at a time to see if it ran worse or the same and every single one seemed to run worse no now im hopping clogged fuel filter is causing this little miss any ideas would be great guys i really do appreciate all the help i've been getting even if im not putting out the results for all the help....

could be about a million things.

always start with the basics, spark plugs, wires, filters, vacuum leaks, etc.
