What is the firing order for a 1992 bronco with an in-line six cylinder Where is the number one plug on the distributer?

Answer 1

If you are referring to the 300 or 4.9 liter in-line 6, the #1 plug is the one at the front of the engine. The firing order is 1-5-3-6-2-4 Distributor rotates clockwise. If you have the plug wires removed and if the #1 plug is not labeled on the distributor cap, you will need to find Top Dead Center (TDC) on the #1 cylinder. Remove all plugs and rotate the engine by hand until you have TDC on #1 cylinder at the compression stroke. A thumb over the plug hole will tell you when you are on the compression stroke as you will feel the pressure. A long screwdriver inserted into the cylinder will tell you when you reach TDC. Once you get TDC on #1, remove the distributor cap and look inside the distributor and the rotor will be pointing at the #1 plug terminal. The next terminal going clockwise will be 5, then 3, 6, 2, and finally 4. Make sure the plug wires do not cross each other and you will be set. Good luck.
