Spark plug firing order?

So we took all the wires off of the distributor cap (I know, don't ask...) What is the firing order of the spark plugs and how can I get the wires back on in the right order?

Spark plugs and wires


It sounds like the spark plug wires are not plugged into the correct place on the distrubutor. take the distributor cap off and crank the engine over. Make a note of which direction the rotor spins. (Clockwise, or Counterclockwise) then find the firing order for that engine. Sometimes the firing order is on the intake manifold. (if you tell me which engine it has, the 4 cylinder 2.0, or the 6 cylinder 2.5; I could post you the firing order). Now on the distributor cap there is one wire post that has the #1 on it, that would be where you put the spark plug wire from cylinder 1. Following the rotation of the distributor rotor, you would put the spark plug wire for the next cylinder in the firing order after the #1 wire, and so on.

Change my spark plugs and distrubutor cap and the 85 ranger want start


You may have got the spark plug wires out of sequence.
Reseat the coil wire going to the center of the distributor cap Check the spark plug wires at the distributor against the firing order as follows:
The spark plug firing order is 1 - 4 - 2 - 5 - 3 - 6 The distributor rotor turns CLOCKWISE The engine cylinders / spark plugs are numbered :
firewall 3 - 6 2 - 5 1 - 4 front

I took of*** my spark plug wires working on my small block 350 pickup and I don't remember the the firing order to put the new wires back on. Is there a diagram anywhere or is it even that difficult to...


Next time number each lead before you remove it and no. the dissy cap as well

The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.
On classic chevy small block engines that use ignition breaker points instead of electronic ignitions, the number one cylinder is the one immediately clockwise of the small metal sash cover on the distributor cap. The firing order starts here. There is no sash cover on the distributor cap for GM HEI electronic ignitions, and the firing order is the same, but starting at the 5:30 position.
The firing order makes sense if you know how the cylinders are numbered. The number one cylinder is the front most on the drivers side and 2 being the front most on the passenger side. From front to back, the cylinders are odd numbered on the drivers side, and even numbered on the passenger side.
See the diagram; Click to open a printable larger image in a new window. The firing order starts with the number one cylinder. We would connect the number one spark plug wire to the distributor cap terminal in the 6:30 position. distributor.pngSince the next cylinder in the firing order is 8 (passenger side rear), we connect the number 8 spark plug wire to the next distributor cap terminal (approximately 7:30 position) in the clockwise direction from number one. You need to be sure you continue the firing order in the clockwise direction around the chevy small block distributor cap from the last installed spark plug wire. Setting the rest of the firing order is just a matter of repetition. Be sure to count the spark plugs from front to back on each side of the motor to identify the correct cylinder number in the firing order.

FIRING ORDERS

To avoid confusion, ALWAYS replace spark plug wires one at a time.

The most important thing to remember about the removal and installation of a distributor, cap or spark plug cable is that all wires MUST be labelled before they are disconnected. Keep in mind that these figures depict a firing order where the distributor cap terminals are relative to EACH OTHER only and they do not necessarily depict the tower positions in relation to the rest of the engine. This is true because any distributor which has been removed and reinstalled may have been installed with the No. 1 spark plug tower at any position (360 degrees) in relation to the rest of the motor, as long as the rotor aligned to the No. 1 tower when the No. 1 cylinder was at TDC of the compression stroke (valves closed, ready for the plug to fire). As long as the remaining wires were connected in the correct firing order sequence (depending on direction of distributor rotation) the engine will run. DO NOT EVER remove more than one wire from the distributor cap at a time unless you tag ALL wires and towers to assure proper installation.

Hi,
I don't know your engine size, but the link below is a picture of the GM small block firing order with distributor.
The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.
