i know if you have the 5.4L V8 you will have coil packs. not spark plugs
Screwed in the heads.
I believe the dealership gets 190.00 time and plugs
on top of the spark plugs in the intake manifold.
Check the Vehicle Emission Control Information ( VECI ) decal located in the front of the engine compartment ( it will show what type of spark plugs to use and the spark plug gap )
they are under the little circle black things which are called coils
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
1 - 5 - 3 - 6 - 2 - 4 ( distributor rotation is CLOCKWISE ) - 300 cubic inch / 4.9 L engine
no spark from the coil, or the icm, or plugs are shot or plug wires, no fuel,no shark no start
I recently had that problem with my Ford f150 '07 truck and it was my spark plugs
Does a 2003 ford expedition have spark plugs?
