I was looking at one of Fords websites and it shows :
For a 1965 Ford Mustang , 3.3 liter / 200 cubic inch inline six cylinder ( .035 inch )
For a 1965 Ford Fairlane , 2.8 liter / 170 cubic inch ( .035 )
For a 1965 Ford F-100 , 4.9 liter / 300 cubic inch inline six cylinder ( medium duty is .030 and light duty is .035 )
So. without knowing which model and engine size it looks like ( .035 inch spark plug gap )
the gap is 5.0
4 - modern combustion engines use 1 spark plug per cylinder. ANSWER The 1994 Ford Ranger 2.3 L has Ford's twin plug ignition system , so there are 8 spark plugs The 94-95 Ranger 2.3 has twin plug system, 2 per cylinder =8
Some auto parts retail websites have spark plug wiring diagrams. One of them, AutoZone, shows the spark plug wiring diagram for the 1993 Ford Tempo 3.0 liter 6-cylinder model.
Obviously- the spark plugs were not the issue :)
An excellent truck.I believe there are 2 sparkplugs per cylinder on that motor, and two sets of distribution units and spark plug wires. I had constant difficulty with my own ranger's electrical system due to moisture buildup in the cap discharge units. If one goes out if affects the other. It is likely that these will need to be replaced - you can find them easily at a junkyard.Follow the spark plug wires back to the other end, where they connect ( on the passenger side of the engine) is the unit I am talking about. It is also possible the spark plug wire is broken.
A 1968 Ford Galaxie 500 with a 390 engine should use a spark plug such as an E3 brand spark plug. This plug should have a tapered seat with 18mm threads.
