2003 Ford E250 Firing Order – It’s important to know which lender (or cylinder Top) is # 1 to help you figure out a beginning point for firing order or just to change the appropriate aspect, such as an Oxygen detector, fuel injector or ignition coil.
In past times everything that was necessary to determine which bank or cylinder brain is number 1 was to see which cylinder brain is located the farthest forward. One that is considered the most ahead (closest to the front side of your engine) is the main cylinder and therefore part is banking institution one.
But many motors these days have cylinder heads that are positioned uniformly, making it harder to determine which is lender # 1 and which happens to be financial institution second. A few popular reasons we need to know this, for example is always to decide Oxygen indicator to replace when you would like B1 S1 (Banking institution One particular Indicator 1), or maybe you’re trying to find an ignition coil to examine to get a P0301 (#1 cylinder misfire saved) misfire code.
