Just remove an ignition coil that you know is good, with a good spark plug and hook up to the wire were the bad one was. Have someone start your truck up for you and if the spark plug fires then the ignition coil that you took off was bad. But before you do that just try a new spark plug that may be the problem.
Unplug the spark plug wire from the spark plug and put a metal screwdriver in the wire and see if you get an arc when you turn the car over. If it does the coil is fine, if it doesnt arc, then you got a bad coil.

the coils on your vehicle are the 'pen' type , one per plug , they are held in place by a screw/bolt and fit directly onto the spark plug , if you need more info please reply
Did u find code p0306 comes up ? Two things can cause this if the plug and coil have been replaced.the intake manifold may be leaking in the area of cyllinder 6 or its a mechanical issue.try doing a cyllinder misfire test and also check the compression on all cyllinders

You need to replace the starter solenoid contacts, or the starter itself.
Note that the starter is UNDER the intake manifold. This is a VERY difficult job, and is not recommended to those who do not have sufficient automotive experience.
If you DO remove the intake, you MUST replace the intake manifold gaskets, or your engine will not run properly, due to air leaks at the intake mating surfaces.
