2005 Silverado Firing Order

I replaced plugs and wires. 1-3-5 on the left and 2-4-6 on the right.... On the distributor cap why does it say 3-1-5 on the left and 2-4-6 on the right? I actually got the 1 & 3 switched at first and corrected my problem but my check engine light is on....? Truck is running fine so I don't understand
Thanks

1983 f150 351w distributor cap placement


I assume its a V8 and probably a 5.0L

5.0= 1-5-4-2-6-3-7-8 firing order

5.0 HO and 351 Windsor share 1-3-7-2-6-5-4-8 firing order

Cylinder numbering:

When looking into the engine bay the number one cylinder should be on your left hand side (left bank) at the front of the engine. The number eight cylinder is on the rear right (right bank) up against the firewall.

Working on a 1973 chevy silverado with 350 v8 motor in it. I'm confused with the distributor wiring to the spark plugs. Can anyone show me how to locate the spark plugs wire and wire them according to...


So far so good. The firing order is 1-8-4-3-6-5-7-2. The #1 wire goes in the distributor at the 6:30 o'clock position and the rest of the wires go clockwise from there according to the firing order. The 6:30 position should be the first one to the right of the window on the cap. Hope this helps.

Looking for distributor wire diagram


If your engine is a four cylinder, the firing order is as follows; from left to right on the block..1-2-3-4...look at the top of the distributor cap: counter clockwise from #1, the order is...1-3-4-2. If your engine is a six cylinder, face the front of the engine...left bank is: 1-3-5...right bank is: 2-4-6...look at top of distributor cap starting with #1...read counter clockwise...1-2-3-4-5-6. Let me know how you make out. Master FixYa...saailer@att.net

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.

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.

I installed spark plug wires wrong on a 4.3 gm motor for 2000 gmc sonoma now it does not start need wire schematic to guide me


Standing at front of truck, looking under the hood.

The closest cylinder to you on your right is #1. #2 is close left. #3 is middle right, #4 middle left. #5 is back right and #6 is back left.

Firing order is 1-6-5-4-3-2. This is the sequence for placing the wires on distributor cap in a clockwise direction. #1 spot on cap is the 3rd post after the wiring harness (clockwise). This post should be closest to cylinder #5.

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

What is the firing order for the 1994 ford taurus 3.8 engine, have just replaced cap and rotor, need order, thought I marked them but engine will not start. Perhaps I was wrong in the order.


Not trying to insult your intelligence, I'm going to get pretty basic here,

Looking at the Front of the engine, the spark plug order is 1, 2, 3, and 4. Front to back.

Looking at the distributor, it has two mounting screws for the distributor cap. One is close to the engine, the other screw is on the other side.

Looking at the distributor cap screw, on the Far side away from the engine, Number 1 spark plug is on the tower to the Left of it.

To the right of this distributor cap screw, is Number 2 spark plug tower.
The rotor turns clockwise.

Again, looking at the distributor from a top view, there is a distributor cap screw at the top, (Close to engine), and a distributor cap screw at the bottom.

Drawing an imaginary line from the top screw to the bottom screw, Number 1 spark plug wire goes to the Left, of the bottom mounting screw.

Firing Order is 1-3-4-2
The rotor turns Clockwise, (To the right)
