Ford 302 Firing Order Diagram – It’s important to know which financial institution (or cylinder Top) is # 1 to assist establish a starting place for firing order or simply to exchange the right portion, just like an Oxygen detector, energy injector or ignition coil.
Before all of that was required to determine which financial institution or cylinder head is # 1 was to determine what cylinder brain is positioned the farthest forward. One that is easily the most frontward (nearest the top from the engine) is the best cylinder and this part is banking institution a single.
But a majority of motors right now have cylinder heads which can be situated consistently, which makes it more challenging to find out which is lender # 1 and that is financial institution number 2.

Things to try out
- 4 cylinder motors also have the #1 cylinder nearest the front side from the engine (just one single bank).
- V-6 or V-8 look for the connect that may be closest to the front side in the engine, when the cylinder heads are even a different way of deciding #1 will probably be necessary.
- Don’t overlook the obvious, review the spark plug wire alone for cylinder numbers.
- Also check the ignition coil for numbers.
- If you have a scan instrument, try disconnecting an oxygen sensor briefly to find out which is B1 or B2. Normally a pending code or tough code will set quickly. Also check out the information monitor of the check out device, the voltage need to generally normal to .5V.
- If all else fails look at the support manual. Numerous online options provide quick access to firing order plus much more at DIY costs.
