2008 Ford 4.6 Firing Order – It’s vital that you know which lender (or cylinder head) is number 1 to assist decide a starting point for firing order or simply to switch the appropriate portion, like an Oxygen sensor, energy injector or ignition coil.
In the past all of that was necessary to find out which bank or cylinder brain is primary was to determine which cylinder brain is situated the farthest frontward.

Four cylinder engines usually have the #1 cylinder nearest to the front in the engine (just one single lender).
V-6 or V-8 seek out the connect that is nearest to the leading from the engine, when the cylinder heads are even an alternate means of deciding #1 will probably be necessary.

Also look into the ignition coil for phone numbers.
When you have a check instrument, attempt disconnecting an oxygen sensing unit in the short term to find out which is B1 or B2. Commonly a pending code or difficult code will set quickly. Also look at the details screen in the check out resource, the voltage must in many instances standard to .5V.
If everything else fails look at the support handbook. Several on-line places offer easy accessibility to firing order and much more at Do it yourself costs.
