Firing Order 2002 Ford F150 5.4 – It’s vital that you know which bank (or cylinder head) is primary to help you decide a starting point for firing order or just to exchange the right component, as an Oxygen sensing unit, fuel injector or ignition coil.
In the past all that was required to determine which lender or cylinder mind is number 1 was to find out which cylinder head is located the farthest frontward. The one which is considered the most frontward (nearest the front of your engine) is the main cylinder and this side is bank one.
But some motors these days have cylinder heads which are situated evenly, which makes it harder to determine which is lender number 1 and which can be lender second. A few popular reasons we should know this, for example is to figure out Oxygen indicator to exchange when you are searching for B1 S1 (Lender One particular Detector One), or maybe you’re trying to track down an ignition coil to inspect for a P0301 (#1 cylinder misfire recorded) misfire code.
