Firing order number one plug?

The firing order is the same, 18436572
But, depending on who made the engine, the firing order may go cw or ccw around the cap. You need to check which way the rotor turns when you crank it, then follow the firing order in that direction. Sometimes the number 1 spark plug tower is marked on the cap, if not, put the number one cylinder on top dead center of compression stroke, which ever coil tower the rotor is leading into is number one, then follow the firing order in correct direction of rotation. You driver side cylinder bank should be numbered, 1357 from front to back, passenger side 2468, front to back.
If you replace plugs and plug wires, one at a time, you won't have this problem. Goodluck.

Here you go. Hope this helps FixYa up.

4-cylinder:

Firing Order: 1-3-4-2

3.1 liter:

Firing Order: 1-2-3-4-5-6

Firing order is 1-6-5-4-3-2. Cylinder numbers are, front to rear: left side (driver) 1,3,5, right side 2.4,6. Distributer numbers are: 1 in front side of cap. numbers run clockwise same as firing order from number one position.

The number 3 plug is the third one back from the front of the engine. They are numbered in order 1,2,3,4,5,6 front to back, this is the cylinder numbers not the firing order. Firing order is 1-5-3-6-2-4 .

Okay, on the photos I am posting, pick the size of motor that you have....since you didn't post it. When you find the right photo of your motor, the numbers on the engine correspond to the number of the spark plug that goes to the coil...1 to 1, 2 to 2 and so on. This is your firing order and will ensure you have the proper spark plug firing from the correct point:



1FZ-FE engine Firing order: 1–5–3–6–2–4Distributor rotation: counterclockwise



5VZ-FE engine Firing order: 1–2–3–4–5–6Distributorless ignition system



2RZ-FE and 3RZ-FE engines Firing order: 1–3–4–2Distributor rotation: clockwise



2RZ-FE and 3RZ-FE engines Firing orders: 1–3–4–2Distributorless ignition system



2UZ-FE engines Firing order: 1–8–4–3–6–5–7–2Distributorless ignition system

The 3.5L (VIN H) engine's unique ignition system has the ignition coils directly over each plug. No spark plug wires are used.




3.5L (VIN H) engine Firing order: 1-2-3-4-5-6 Distributorless Ignition System



The firing order for the 3.1L VIN M, 3.4L VIN E, 3.4L VIN X and 3.5L VIN H engines is 1-2-3-4-5-6. The right bank cylinders are on the cowl side (rear) of the engine compartment and are numbered 1,3,5, left bank cylinders on the front side of the vehicle, are numbered 2,4,6.

I hope help you with this, remember rated this help. Good luck.

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.
