1-8-4-3-6-5-7-2 is the firing order, I tried to answer your question but it was locked by someone else.

You could have mixed up the order of the spark plug cables causing the firing order to be wrong. What is the exact year, make, model, and engine size of your truck?

Recheck the order, 18436572 clockwise. number 1 should be the one closest to the coil tower.

I just changed the spark plugs in my 2004 Ford BA Falcon and now it wont start!


Sounds like you have crossed the spark plug wires...(wrong firing order:) Check with the store where you purchased the new plugs...they should be able to provide the correct firing order...also you must locate cylinder #1 to begin...and confirm the pattern of the firing order...sounds harder than it is...Hope this helps.

Change spark plugs and ignition wires and now it wont start


If you didn't change the wires one at a time,you are probably mixed up in firing order. Pull them all,get a picture of order from your local parts house and start over.

Hi, Sound like you have the firing order wrong try changing the plug wires around or look on side of engine it normally is marked just below the spark plugs the numbers give you the firing orders IE: 1 2 3 4. Hope this helps give me feedback please. Thanks, Malcolm Campbell.

My husband did a tune up on my car yesterday and now it wont start it will turn over like it wants to start but it wont he said that its miss firing we have bought 3 new coil packs and still will not start...


If your car is miss firing and your husband changed the coil packs,the wires leading from coil packs to sparkplugs must have got crossed.This will change car timing which will result in the car miss firing.He needs to go over wiring and correct problem for car to run right.You can go online to autozone.com and type in Info about car to get the correct wiring layout.Your problem isnt the new plugs n wires.Its the wiring layout.

Just changed out my spark plugs, wires, distributor cap and rotor. Now the car wont start, what is the problem ?


Recheck the firing order of the spark plugs and wires. you might have connected them wrong. Can't tell you the firing order since I don't know what kind, make, or year of your vehicle.

Make sure wires are in correct order for firing. Also make sure they snap down when placed on.
