69 Ford 302 Firing Order – It’s crucial that you know which banking institution (or cylinder head) is primary to help you decide a starting point for firing order or simply to switch the proper aspect, as an Oxygen sensor, energy injector or ignition coil.
In past times all that was necessary to determine which bank or cylinder mind is primary was to find out which cylinder mind is situated the farthest forward. The one that is considered the most ahead (nearest the top of the engine) is the number one cylinder and that side is lender one.
But many motors nowadays have cylinder heads which can be located uniformly, that makes it harder to determine which is bank # 1 and which can be lender second. A few common motives we have to know this, as an example is to determine Oxygen indicator to replace when you are searching for B1 S1 (Bank One Detector A single), or maybe you’re seeking to locate an ignition coil to examine to get a P0301 (#1 cylinder misfire saved) misfire code.
What you should attempt

- V-6 or V-8 seek out the plug that is certainly closest to the leading from the engine, if the cylinder heads are even an alternate way of identifying #1 will probably be essential.
- Don’t disregard the apparent, check up on the spark plug cable alone for cylinder amounts.
- Also check the ignition coil for figures.
- For those who have a scan instrument, consider disconnecting an oxygen detector for the short term to determine which is B1 or B2. Usually a pending code or hard code will set quickly. Also consider the information display of the check out resource, the voltage need to typically go into default to .5V.
- If all else breaks down look at the service manual. Several online places supply easy access to firing order plus much more at Do it yourself costs.
