Ford 5.4 3v Firing Order – It’s important to know which bank (or cylinder Top) is # 1 to aid figure out a place to start for firing order or just to change the appropriate part, as an Oxygen indicator, gasoline injector or ignition coil.
Before everything was required to find out which financial institution or cylinder brain is number one was to find out which cylinder mind is placed the farthest forwards. The one which is the most frontward (nearest the top from the engine) is the main cylinder and therefore part is banking institution one.
But many motors these days have cylinder heads which can be placed evenly, which makes it tougher to find out which is bank number 1 and which happens to be lender # 2. A number of common reasons we have to know this, as an illustration is always to decide Oxygen sensor to change when you would like B1 S1 (Bank 1 Indicator A single), or maybe you’re seeking to track down an ignition coil to inspect for a P0301 (#1 cylinder misfire captured) misfire code.
