2004 Ford F150 4.6 Firing Order – It’s important to know which bank (or cylinder head) is number 1 to help decide a starting place for firing order or maybe to change the proper portion, like an Oxygen indicator, fuel injector or ignition coil.
In past times all of that was required to determine which lender or cylinder brain is primary was to see which cylinder mind is positioned the farthest forwards. The one that is easily the most ahead (nearest the top of the engine) is the top cylinder which aspect is financial institution 1.
However, many engines right now have cylinder heads that happen to be placed evenly, which makes it more difficult to determine which is bank number 1 and which is lender # 2. A couple of typical good reasons we have to know this, as an example is always to establish Oxygen indicator to exchange when you are interested in B1 S1 (Bank 1 Indicator 1), or if perhaps you’re looking to locate an ignition coil to inspect for any P0301 (#1 cylinder misfire documented) misfire code.
Things to try out
Four cylinder motors also have the #1 cylinder nearest the front side of the engine (only one lender).
V-6 or V-8 seek out the connect that may be nearest to the leading in the engine, in the event the cylinder heads are even a different strategy for identifying #1 will probably be necessary.
Don’t overlook the clear, check into the spark plug cable itself for cylinder figures.
Also look at the ignition coil for amounts.
For those who have a check out instrument, attempt disconnecting an oxygen sensor briefly to determine which is B1 or B2. Normally a pending code or challenging code sets rather quickly. Also look at the information monitor of your check out device, the voltage must in most cases standard to .5V.
