How do I put in an ignition coil for plug number 1?

It is one of the two. First thing is to remove and check the plug for gap and condition. Then reset the code and run the vehicle. If it does it again, you swap the coil pack from Number 4 to Number 1. If the misfire them moves to number 1 you know the coil pack is the issue. Sometimes just moving it will fix the issue as the connections get remade.

Follow the spark plug leads back to the ignition coil, number 1 will be the plug at the front of the engine as you look at it from under the hood

the code means "ignition coil A / primary circuit malfunction". It usually leads to a car misfiring or running rough. The coil on plug (cop) ignition system has a short or open circuit. The last number of the code tells you which coil wire is malfunctioning. In your case it is coil number 1, which should be the number 1 cylinder. These coils take the place of spark plug wires. there are 2 wires coming off of these coils. One goes to the battery, the other the cars PCM. Check that the connection is good on the spark plug, if that doesn't fix it, then check the wires for a break in the wires. It could also mean that the coil (cop) is no good and will have to be replaced. These coils (cop) are all attached to your spark plugs, so they are easy to find. Good luck.

STANDING FRONT OF VECHICLE CYLINDERS FACING YOU ARE 4 5 6 AND BACK CYLINDERS IS 1 2 3 NOW ON PIECE PAPER LOOKING AT IGNITION COIL PACK FACING YOU WRITE BACK NUMBERS 123 AND UNDER THAT NUMBER 1 2 3 WRITE FRONT NUMBERS 5 6 4 THATS YOUR COIL PACK PLUG WIRES LOCATION. LIKE I SAY 5 6 4 IS PLUGS WIRES LOCATION FACING YOU AND BACK NUMBERS 1 2 3 PLUG WIRES LOCATION ON COIL PACK. FIRING ORDER IS 1 4 2 5 3 6

P0301- Cylinder Number 1 Misfire Detected

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Most likely your issue is with cylinder number 1. Follow the info I have provided and you should be able to solve this issue.

2.3L 4 cylinder? After removing the plastic engine cover, look at the top of the ignition coil.


It should be numbered 1 through 4.

This is plug number 1 on the engine:


Just wire them 1, 2, 3 and 4 to the corresponding numbers on the ignition coil.

best wishes

The firing order is 1-3-4-2

Number one is the one at the pulley end of the motor and number 4 is at the flywheel end of the motor.

System uses a Distributorless Ignition System (DIS) with 2 ignition coils. Cylinders No. 1 and 4 use the same ignition coil. Cylinders No. 2 and 3 use the same ignition coil.

For the 1993 Chevy Lumina:
I do not know if you have the 2.2L In-Line 4 Cylinder, 3.1L V6, or 3.4L DOHC V6 Engine; however I have included all below.

For the 2.2L (4-Cylinder)
Firing Order:
1-3-4-2
Cylinders:
......(back)
1.....2.....3.....4
......(front)
Ignition Coil Connections:
o <---4
...o <---1
.........
......o <----3
.........o <----2

For the 3.1L V6:
Cylinders:

5.............6
3.............4
1.............2
....(front)
Ignition Coil Connections:
.|.1..4.|..|.6..3.|..|.2..5.|


For the 3.4L DOHC V6:
Firing Order:

There are no "special" tools required. Here is how you would do it:

NOTE: This engine is equipped with an aluminum cylinder head. Allow the engine to cool before removing spark plugs. Removing the spark plugs from an engine at operating temperature may damage the spark plug threads in the cylinder head. Also be sure to clean any dirt or debris from around spark plug holes prior to removing spark plugs.

I also recommend putting a small amount of anti-seize compound on the threads of the spark plugs when installing. Be careful not to under or over-tighten because cylinder head damage could result. If you have access to a torque wrench, the specification is 11 foot pounds.

1. Disconnect the ignition coil electrical connectors.
2. Carefully release the number 1 spark plug wire from the clip on the number 2-3 ignition coil.
3. Remove the 2 bolts from each ignition coil.
4. Remove the number 1 spark plug wire and the number 1-4 ignition coil from the spark plugs.
5. Remove the number 2-3 ignition coil and the number 3 spark plug wire from the spark plugs.
6. Remove the spark plugs from the cylinder head.
7. Reverse proceedure to install.

HI......
OK. just follow the number on the ignition coils.
And the number on the cylinders are.
The FIREWALL side are 1,3,5, Starting from the belts location.
The RADIATOR side are 2,4,6, Starting from the belts location.
The coil with number 1 go to cylinder 1. as the same way the rest of the coils and cylinders.

OK... I hope this solve your question .

THank you for use fixya.
