This sounds like a crossed sparkplug wire, start by making sure the firing order is correct, if theres a sparkplug wire in the wrong spot this would cause hard starting and the backfiring, so check the firing order first, i would of given you a firing order diagram but you forgot to list the year, make , model and the engine size. good luck and have a good day.

LOOK ON DECAL ON RADIATOR OR VALVE COVER FIRING ORDER IS THERE ,GO TO PEP BOYS FOR MANUEL

Just follow the firing order starting with the white dot as number one.

#3 sparkplug is not firing at peak performance.
The engine block sparkplug hole had to be re-threaded in order to accept an adapter for the replacement spark plug. The sparkplug is sitting "higher" in the cylinder than the others (not as efficient).
It may even be a different sparkplug altogether in order to accommodate the adapter.

Add a silicone insulator gel (AutoZone $2) inside both boot ends of the sparkplug wires and re-seat them all.

Do you mean you need a diagram for the spark plug wires? The firing order of the engine is usually molded into the factory intake manifold, and most distributor caps have the #1 cylinder location marked on it. For a more detailed look at it, try to find a repair manual for your truck.
