Where is the firing order on a distributor cap?

The firing order on a distributor cap for an 8 cylinder engine is 1 2 3 4 5 6 7 8. Inside the distributor cap is the rotor. The rotor strangely enough got that name because it rotates. As it rotates it passes a spark though to each of the spark plug wires that are plugged into the top of the distributor cap.

What determines the firing order?

Firing Order is Determined by the Number of Cylinders contained within that engine & Crankshaft Alignment/Offset of each Crank-Journal, during the Design/Manufacturing Process. The firing order is determined when the engine is DESIGNED, so as to make it run as efficiently and as smoothly as possible.

What happens if you hook up spark plug wires wrong?

When the firing order is wrong or delayed, the engine does not run properly. The spark may be delivered to the cylinder when there is no fuel/air mixture or before it is properly compressed. One symptom of an incorrect firing order is the engine does not run. Turning the ignition does not start the engine.

Will wrong firing order damage engine?

Yes. Everything else remaining same, if the firing order is changed, it can lead to engine troubles sooner. This is because the firing order is chosen to minimize unbalance forces acting on the crank shaft.

What do spark plug wires connect to?

High tension leads or high tension cables or spark plug wires or spark plug cables, colloquially referred to as HT leads, are the wires that connect a distributor, ignition coil, or magneto to each of the spark plugs in some types of internal combustion engine.

How do I know if my firing order is wrong?

When the firing order is wrong or delayed, the engine does not run properly. The spark may be delivered to the cylinder when there is no fuel/air mixture or before it is properly compressed. One symptom of an incorrect firing order is the engine does not run. Turning the ignition does not start the engine.

What regulates the ignition timing?

In most modern engines, ignition timing is controlled by the engine's computer.

Can you change firing order?

You cannot change the firing order as it is already set out in the design of the crankshaft and cam shaft relationship. The usual firing order of a 4 cylinder in line engine would be 1,2,4,3. but it could also be designed as 1,3,4.2 which is the reverse firing order.

What voltage is spark plug firing?

Spark plugs usually require voltage of 12,000–25,000 volts or more to "fire" properly, although it can go up to 45,000 volts. They supply higher current during the discharge process, resulting in a hotter and longer-duration spark.
