What is the firing order?

The firing order is in a manual and sometimes cast on intake if cast aluminum. But if plastic I will send it in picture. There are two different VIN numbers for plug wire placement. See pictures.

I just bought this vehicle (Sport model). The truck has a miss in it. It will start right up, but idles rough. The truck has sit up for 2 years. I replaced the coil, and the fuel pump. The wires look new, and the only thing I can think of, is the firing order is off, or the plugs maybe bad from sitting. I would appreciate any input. Thanks. Randy.

I paid a guy to tune up my explorer. Which he ripped me off. Instead of putting the brand new plug wires on that I bought for my explorer, he put used plug wires from a completely different vehicle on, and did not get the firing order correct. I now have the correct plug wires, but I don't know the correct firing order. My Explorer has a 4.0l SOHC V6 engin.

Yes it does. My next dumb question is. On the diagram of the ignition coil. Which side of the diagram is the connection from the ignition module located. I really miss the days of the distributor cap and rotor button.

Tiny

Ah, no such thing as a dumb question. In fact, this is a really good question, hehe. I think the picture below will help you out. Just in case you can't see the writing on the wires, the 3 wires on the left of the picture are 1 (starting at front where hand is) , 2 and 3. The wires on the right side of picture are 5 (starting at the front again) , 6 then 4.

You should be able to find the connector from this picture.

That helps alot. On my ignition coil, the connector is on the left side under the #2 wire

Yeah, I think I can make it out in the above picture as well. Sounds like you have it figured out now.

Good luck and if you need any further assistance just let me know. :)

Think you. I hope it does. The engine is miss firing on cylinders 2, 3, 4, 5, and 6. The truck has no power and is dranking gas like its going out of style. If this doesn't work I'm going to have a compression test done. Then I've gotta find where I'm losing coolant. Its not leaking under the truck and its not in my floorboard, but I'm dumping 2 gallons every 4 days into the radiator.

Coolant leaking with no signs huh. You may want to check out your oil level. Is it milky looking? Over filled? I believe you may have a blown head gasket or manifold gasket. This will let coolant into the combustion chambers and cause misfireing. It will also cause the coolant to leak without a noticeable sign (drips, wet spots.). Sounds like you should go ahead and get it pressure tested. May also be a cracked head, but this will usually result in smoke as well.

Ok, now you're just scaring me. Lol
But I've been thinking I might have a blown head gasket for awhile. Think you again
