The V6 engine firing order is ( 1 - 4 - 2 - 5 - 3 - 6 ) in your case it is a 2.9 L / 3.0 L or 4.0 L The engine cylinders / spark plugs are numbered 1 , 2 , 3 from front to rear on the passenger side of the engine and 4 , 5 , 6 from front to rear on the drivers side of the engine The 2.9 L and 3.0 L engines have a distributor , the distributor rotor turns CLOCKWISE , and the marked # 1 position on the distributor cap is installed facing to the rear towards firewall / passenger side The 4.0 L has a coil pack ( DIS - Distributorless Ignition System ) The COIL PACK TOWERS are numbered coil---------3-----4 pack--------2-----6 plug---------1-----5

That's Fords twin plug ignition system , so your Ford Ranger 4 cylinder has ( 8 ) spark plugs and spark plug wires
In a 1997 Ford Ranger : The 2.3 liter four cylinder with Fords twin plug ignition system has ( 2 coil packs ) and ( 8 ) spark plug wires for the eight sparkplugs The 3.0 liter and the 4.0 liter V6 engines have ( 1 coil pack ) and ( 6 ) spark plug wires for the six spark plugs
P0300 means random misfire detected which probably has to do with the spark plugs or the plug wires
distributorless ignition system - the coil pack(s) with the towers where your spark plug wires are connected - the other ends of the spark plug wires are connected to the spark plugs ( on the 2.3 L and 4.0 L engines in 1993 )
The spark plug number that is in my 2003 Ford Ranger XLT is: AGSF34FP - Motorcraft.
