Chevy V6 3.4 distributor firing order

Just follow the firing order of 1-3-4-2. Take off the distributor cap to see which way the rotor spins when the engine is cranking, either clockwise or counter clockwise. then, with number 1 cylinder and it's position on the distributor cap tower, you just use the firing order to fit the wires 1-3-4-2.
So you know the engine cylinders are numbered 1,2,3 4-front to back of engine. If you need to find where #1 on the distributor tower is, you have to find Top Dead Center of the compression stroke on number 1 cylinder. Then the rotor on the distributor shaft will be pointing directly to the #1 cylinder's tower.

Post back if you need help finding TDC of compression stroke on #1 cylinder.

I've uploaded a diagram that gives you the firing order for the 96 Chevy Cheyenne. The best way to find out which is number one in the firing order is to following the spark plug on the engine block back to the distributor cap. Number 1 is on the right side, closest to the front of the engine. Best of luck!

18436572. is the cylinder firing order. 1 is on the front divers side, 2 is on the front passenger side and so forth. On the distributor, 1 is at the front of it, pointing towards the number one cylinder. 8 is the next left one. and so forth.

If it is the 1.6 liter 4 cylinder here is a diagram for you. Hope this helps.



Sorry it wouldn't let me post it any bigger. If you need more help I can forward you a link.

1-8-4-3-6-5-7-2 is the firing order it rotates clockwise and #1 on the cap usually faces towards cylinder 1.number 1 cylinder is the front cylinder on the drivers side of the motor and it goes 1-3-5-7 front to back on that side of the motor.and 2-4-6-8 on the passenger side of the motor front to back.

This method is good for the firing order on all chevy small block v8 engines from 265 cubic inches to 400 cubic inches. This would include 265, 283, 305, 327, 350, 400 cu. in. chevy small block v8 engines.

Let's cover some safety concerns first. If you try to troubleshoot a mixed up firing order with the engine running, you could be in for a serious shock,.. literally. You can do it, with certain precautions, but you really don't need to check the firing order with the engine running. You definitely don't want to try checking the firing order if you are wearing any kind of pacemaker or sensitive electromechanical prosthesis. The voltage coming out of the ignition coil is in the thousands. Common sense dictates that you wouldn't stick a knife in an electrical outlet, so you wouldn't want to take chances with being shocked by the electrical discharge from your classic chevy's ignition coil either. See the diagram:




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.

You didn't post your engine size so please use the appropriate diagram:




GM (Cadillac) 250 (4.1L) V8 .GM (Cadillac) 273 (4.5L) V8 .GM (Oldsmobile) 307 (5.0L) V8 .GM (Oldsmobile) 350 (5.7L) V8 w/EFI.Engine firing order: 1-8-4-3-6-5-7-2 .Distributor rotation: counterclockwise





GM (Buick) 252 (4.1L) V6 .Engine firing order: 1-6-5-4-3-2.Distributor rotation: clockwise





GM (Cadillac) 368, 425, 472, 500 V8.Engine firing order: 1-5-6-3-4-2-7-8.Distributor rotation: clockwise





GM (Cadillac) 429 V8.Engine firing order: 1-8-7-2-6-5-4-3.Distributor rotation: clockwise

For a 1985 Chevy S10 with a 2.8L engine the firing order is: 1-2-3-4-5-6 The Distributor rotation is clockwise.Take off the cap and bump engine till the rotor points to the no. 1 plug. this is the no.1 contact on the cap. follow rotation around the cap in order. {ie. 2,3,4 ect.} hope this helps.

Firing order is 1-6-5-4-3-2. Distributor cap should be numbered. Number one cylinder is front on driver's side (3 and 5 follow on same side). Number 2 is front on passenger's side (followed by 4 and 6).
