How do you put the spark plug wires back in the correct order if you forgot the right order by not marking them???


The oil should be labeled 1-6. The spark plugs on the front of the engine ( radiator side) are from the passenger to the drivers side 1-3-5. The cylinders on the back side of th engine are from passenger to the drivers side 2-4-6. Put the worse from the cylinder to the corresponding number on the coils. If your coils are not labeled I would need to know the eight letter of your vin number to get you the correct coil numbers.

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.

Change plugs and wire and engine will not acclerate. This is a built 350 short block chevy with pro charger.


350 Chevy engine in what? 1990 Corvette? Who built it, did you?

Sounds as though you have plug wires wrong.
Firing order is 1-8-4-3-6-5-7-2

Distributor Ignition System:
Distributor rotates Clockwise. (Rotor)
Find Number 1 tower on distributor cap, go Clockwise with Firing Order.

Distributorless Ignition System:
VIEWING the engine from the Front of the car.

Spark plug wire connections along the back, starting from Left side going to Right side;
2-3-7-4

Spark plug wire connection towards the Front of the engine;
6-1-5-8

(To guess I would say you have 5 and 7 wires switched)

Left side cylinder order is 1-3-5-7, going from front to back.
Drivers side is Left side.
Right side cylinder order is 2-4-6-8, going from front to back.

I hooked up the spark plug wires wrong on the distrator cap it is a 1988 4.3L 6cyl how can i find a diagram to fix this problem or tell me hoe to fix it


find the firing order which is usually on the intake manifold,put the crankshaft on 0 degrees top dead center,pull off the distributor cap and mark where the rotor button is pointing,start #1 cylinder at that spot(which that spot should be pointing towards the rear of the distributor),and # 1 cylinder is front of engine on the drivers side then it goes next 1 back #3 then # 5,and the passengers side front is #2, then #4,then #6 towards the back,and the firing order goes clockwise on the distributor.if it spits and sputters or back fires,then the timing firing order is off 180 degrees,so move every wire to the exact opposite on the cap,so your #1 plug wire will be opposite from where you put it first.then double check the firing order and all plug wires then try it.the firing order is:165432,i still dont know how to send pictures.

I replaced my spark plug wires on my 1996 chevy truck. may have crossed one,need a diagram from the spark plugs to the distributer cap.


Since you didn't state whether it is a V6 or V8, I'll give you both.

V6 -4.3Liter
Firing Order is 1-6-5-4-3-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap, faces the front of the engine.

->Drivers side, spark plug order in engine, starting from the Front going back:
1-3-5
->Passenger side, spark plug order in engine,
starting from the Front going back:
2-4-6

If it's Electronic, the distributor cap has a Left side, (Drivers side), and a Right side, (Passenger side)
Starting from the Front, going back on the Left side,
3-1-5
Starting from the Front going back on the Right side,
2-4-6

V8-5.0, 5.7, and 7.4Liter
Firing Order is 1-8-4-3-6-5-7-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap,
faces Front, towards the Drivers side.

Electronic distributor cap has two sides. Drivers, (Left), side and Passenger, (Right), side.
Starting from Front going back on Drivers side,
1-7-3-5
Starting from Front going back on Passenger side,
8-2-4-6

Spark plug order in engine, starting from Front going back, Drivers side:
1-3-5-7
Spark plug order in engine, starting from Front going back, Passenger side:
2-4-6-8

Ignition Wiring


Hi,

To my knowledge, firing order is 1-8-4-3-6-5-7-2 clockwise on the distributor cap with the Number 1 post pointed towards the Number 1 cylinder. The cylinders are numbered 1-3-5-7 (front towards the back) driver side while the passenger side/bank are numbered 2-4-6-8 (likewise front to back).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
