2009 Ford 5.4 Firing Order – It’s vital that you know which lender (or cylinder head) is number 1 to aid establish a beginning point for firing order or just to exchange the right part, as an Oxygen detector, gas injector or ignition coil.
Previously everything was necessary to find out which banking institution or cylinder mind is number 1 was to determine which cylinder mind is located the farthest frontward. One that is considered the most forward (nearest the top from the engine) is the number one cylinder and this area is bank one.
But many engines these days have cylinder heads which can be placed equally, rendering it tougher to find out which is financial institution # 1 and which can be bank second. A number of common good reasons we should know this, for example is always to determine Oxygen indicator to switch when you would like B1 S1 (Banking institution 1 Detector 1), or if you’re seeking to locate an ignition coil to inspect to get a P0301 (#1 cylinder misfire saved) misfire code.
