Engine firing order please?

Here is the engine firing order for both diesel and gas engines. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

I need to know the engine setup to place the plug wires in the correct place.

I have found this firing order for you (below). Please let us know if you need anything else to get the problem fixed.

I am looking for a diagram for the plug wires to the distributor cap connections. I know the firing order is 1-8-4-3-6-5-7-2. While replacing the (crab type) cap, rotor, plugs and wires, I messed up bad by not labeling the wires on the cap. The engine is a Vortek 5.7L 350. It is a K1500 4X4 automatic. Any help you can provide would be greatly appreciated. Thank you

Hello, Here is the spark plug to distributor wiring diagram.

Larger version below Please let us know if you need anything else to get the problem fixed. Cheers

Thank You. Just to be sure, I connected wire one to cap position one, and so on. Is this correct? The service engine light was illuminated prior to this. I hooked up my Digital OrbitII Code Reader, and it displayed P0300 - Random/Multiple Cylinder Misfire Detected. This was before I changed the wires per your diagram. I believe I need to figure out how to clear the code, and scan it again. Lastly, I noticed a strong gas smell when I fired it up, and a grayish/black smoke came out of the tailpipe. If you think I should do something else, please let me know, otherwise, I appreciate your response and help. Aloha from Hawaii!

Yes, just match up the number 2 to 2 3 to 3 etc. The smell of gas may just be do to the misfire, so complete the plug wire and see what happens. Your scanner may have a way to clear the codes check the manual for it. Post finding here.

Code cleared, no new codes. Gas smell gone, and no smole from tailpipe. All in all, everything works great! Thanks for the help! :)

Why does the number pattern on the cap not match the firing order?

Does the diagram also apply to the 5.0l Vortec? I have a 1999 k1500 with the 305 that is putting out the same code, so if the diagram is also for the 5.0 Vortec i will check my plug wires. Thanks in advance.

Could you give me the firing order for this truck? Because I put spark plug wires on wrong.

Here is the firing order for your truck.

2, 4, 6, 8, Right Bank on the top.

1, 3 5, 7, Left Bank on the bottom.

The Distributor rotation on the right is 8 2 4 6 on on the left is 1 7 3 5.

Hope this helps you.

i just changed the spark plugs, wires and battery in my pickup, now it won't start. i think i got the firing order wrong can you help?

Sure. For the 4.3L engines: 1-6-5-4-3-2 distributor rotation: Clockwise.

For the 5.0L, 5.7L and 7.4L engines: 1-8-4-3-6-5-7-2 distributor rotation: Clockwise.

Hope this helps. Thanks for using 2carpros.com!

what is the firing order for this truck? Thanks!!

i do not know off the top of my head, but look real close to the distributor cap it is marked right on it. The drivers side front cylinder is number one and pass front cylinder is number two. So drivers side is 1-3-5-7 and passenger side 2-4-6-8.

I changed my plugs and wires, and it started fine and ran ok except for a stuttering at acceleration. I went to Auto Zone and they had me rewire the plug wires. I did this and now it wont start or anything. Is there anywhere I can find correct distributor cap to plug wiring diagram?

You got it

thank you for the diagram of the plug wire. it helped out a lot and I got the truck running again. I am going to reccomend you to everyone I know.

does not crank but turn over and back fires also what is the fire order

Hi, your saying it cranks good, but won't start? The litre size is on the diagram. C1500

Changed plugs and wires and got firing order wrong at the distributor initially, checked your forum, then got correct order, I think. Now I have little power and repeated back-fires. Any suggestions, kind of stuck where I'm at, literally!
Thanks in advance!

Good afternoon,

I attached the diagram for the cylinder location and wire location below for you.

If you have the firing order correct, I would check the gap on the plugs to be sure they are correct.

Inspect the inside of the distributor cap as well for any cracks or carbon tracking. That will also cause a backfire.
