22re fire order

Typically, the one in the front (i.e opposite of the output shaft) is #1. This is true even in Classic SAABs: Even though #1 is up against the firewall, that is still the "front" of the engine, as the output shaft is at the front (north) end of the car.

The 22s are typical engines, firing order is 1 3 4 2. If you picture the position of the pistons in your mind, with #1 at TDC when it fires, you'll get a good idea of how the spark follows the revolution of the crankshaft.

Also, if you're using factory wires, they should be at obvious lengths

*and* numbered, which makes it a pretty fool-proof operation to reinstall. [remembers that there is a good tutorial on engines at a how things work site, finds it:]

Hi, I changed my distributor and rotor, unfortunately someone went ahead of me and pulled the plug off. Now, the problem is, I don't know the fire order, on my new cap I have the numbers 1,2,3,4 written on them, and considering my engine being a in-line

4, wich is actually the first cylinder? The one in the back? Or the one in front? Anyway, any help on this would be greatly appreciated. Thanx Matt

Thanx a lot! I got it running on the first shot! I'm gonna be remembering that one for later use. Thanx again Matt

If you forget again, the wording "Firing Order 1-3-4-2" is usually cast right on the side of the engine block, in big letters. ;-)

Are there any gasoline 4 cyl engines with a different firing order?

Insp. Gadget wondered:

Yes, there are some Ford 4 cylinder engines that use 1-2-4-3 (I think the Pinto and perhaps Mustang II engines used that, if memory serves). You could also conceivably use 1-4-3-2, but I think I've seen that only as part of the progression in those odd-ball Audi 5-cylinder engines, or maybe motorcycle engines.

And, of course, when using Direct Ignition, you can fire two cylinders at once in opposing pairs, as the spark on the exhaust stroke is essentially wasted.

But, fortunately, for 99% of the people out there, the firing order is clearly obvious on the block, around the timing mark, or by looking at the distributor.

The Ford Model A was 1-2-4-3 if I remember right...

VW 4-cylinder engines (the pancake variety) have a 1-4-3-2 firing order.
