03 Ford Ranger 3.0 Firing Order – It’s vital that you know which banking institution (or cylinder head) is # 1 to help determine a starting place for firing order or just to exchange the proper aspect, like an Oxygen detector, fuel injector or ignition coil.
In past times everything was required to find out which banking institution or cylinder brain is number 1 was to find out which cylinder brain is placed the farthest ahead. One that is considered the most forward (closest to the top in the engine) is the main cylinder and this area is financial institution one.
But a majority of engines these days have cylinder heads which are located equally, that makes it tougher to find out which is bank # 1 and which happens to be bank # 2. A number of common reasons we must know this, as an illustration would be to establish Oxygen detector to switch when you are looking for B1 S1 (Banking institution 1 Sensor 1), or maybe if you’re trying to find an ignition coil to inspect for the P0301 (#1 cylinder misfire saved) misfire code.
