2003 Ford Ranger 3.0 Firing Order Diagram – It’s important to know which lender (or cylinder Top) is number 1 to help figure out a beginning point for firing order or just to switch the correct component, such as an Oxygen sensing unit, fuel injector or ignition coil.
In past times everything that was essential to determine which banking institution or cylinder mind is primary was to see which cylinder head is positioned the farthest ahead.
