1993 Ford Ranger 4.0 Firing Order – It’s important to know which lender (or cylinder Top) is number 1 to help figure out a place to start for firing order or just to change the correct component, such as an Oxygen sensing unit, fuel injector or ignition coil.
In past times everything that was needed to determine which bank or cylinder brain is # 1 was to see which cylinder mind is situated the farthest forward. One that is the most forward (nearest the front from the engine) is the best cylinder and that aspect is bank a single.
But a majority of engines nowadays have cylinder heads which can be placed uniformly, making it more difficult to determine which is lender primary and that is financial institution second. A number of popular good reasons we need to know this, as an illustration is to determine Oxygen indicator to change when you are interested in B1 S1 (Banking institution A single Sensing unit 1), or maybe if you’re looking to track down an ignition coil to inspect to get a P0301 (#1 cylinder misfire captured) misfire code.
