2002 Ford Ranger 3.0 Firing Order Diagram – It’s essential to know which bank (or cylinder head) is number one to help you figure out a starting point for firing order or just to replace the correct part, as an Oxygen indicator, energy injector or ignition coil.
Before all that was needed to find out which banking institution or cylinder head is number one was to determine what cylinder head is located the farthest forward. The one which is regarded as the forward (closest to the front side of the engine) is the best cylinder and this area is bank one.
However, many motors nowadays have cylinder heads which can be located equally, that makes it harder to find out which is banking institution # 1 and which happens to be bank second. A few common reasons we should know this, as an illustration is usually to determine Oxygen sensor to change when you are looking for B1 S1 (Banking institution 1 Indicator One), or maybe if you’re trying to locate an ignition coil to examine for a P0301 (#1 cylinder misfire documented) misfire code.
