Screwed in the heads.
they are under the little circle black things which are called coils
i know if you have the 5.4L V8 you will have coil packs. not spark plugs
sounds like the motor is running lean, not enough fuel.
I believe the dealership gets 190.00 time and plugs
thanks
Yes , the 4.6 liter V8 engine in a 1999 Ford E-150 has ( 8 spark plugs )
on top of the spark plugs in the intake manifold.

There are a couple of a reasons why a 1994 Ford F150 truck will not start. The truck may have a dead battery or the spark plugs need to be replaced.
Their are two valve covers on each side the four spark plugs are mounted in the engine block just below each of the Valve covers
no spark from the coil, or the icm, or plugs are shot or plug wires, no fuel,no shark no start
