2010 Ford F150 5.4 L Firing Order – It’s essential to know which bank (or cylinder head) is # 1 to help you establish a starting point for firing order or perhaps to exchange the correct part, as an Oxygen sensing unit, energy injector or ignition coil.

One which is regarded as the frontward (closest to the top of your engine) is the number one cylinder and therefore area is banking institution one particular.

Four cylinder motors usually have the #1 cylinder nearest to the front side of the engine (just one single bank).
V-6 or V-8 search for the plug that is certainly closest to the top of your engine, in case the cylinder heads are even another strategy for identifying #1 will probably be necessary.
Don’t disregard the apparent, check on the spark plug wire by itself for cylinder figures.
Also look into the ignition coil for figures.
For those who have a skim tool, attempt disconnecting an oxygen sensor for the short term to find out which is B1 or B2. Normally a pending code or tough code will set rather quickly. Also glance at the data screen of the check resource, the voltage need to typically default to .5V.
