My check engine light says that my primary and secondary cylinders arnt firing, can anyone tell me the firing order so I know what ignition coils to change

The car needs carlibration,the code means random cylinder misfire.fuel line need and MAF need check

you change the coil but not the module or it is a coil pack assembly
module is the primary circuit and coil is secondary circuit you need the both to fire at cylinder

Cylinder 1 is the first one on the passenger side of the engine (nearest to the crank pulley,belts etc.) the next one over is #2 etc.

yes, the po351 code is Ignition Coil A Primary/Secondary Circuit Malfunction.

Same as Ford Escape.
P0351 - Ignition Coil A - Primary/Secondary Circuit

Cylinder #1, Pin 26 at the PCM, computer.

I would replace the coil on the plug (COP) for that cylinder and see if its' ok. If not, then it is possible that the bad coil took out the driver in the PCM. The test at Pin 26 to see if the light blinks, must be done with the correct tester or it will damage the PCM.

Hope it's the coil.

report results.

4 cylinder or 6 cylinder engine?

P0354 - Ignition Coil D Primary/Secondary Circuit Malfunction.

Description of DTC:
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Symptoms:
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation
- Check Engine Light On
- No spark

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or ECM

Possible Solutions:
- If damage, repair ignition coil circuit
- Replace ignition coil
- Replace PCM or ECM


P0355 - Ignition Coil E Primary/Secondary Circuit Malfunction.

P0356 - Ignition Coil F Primary/Secondary Circuit Malfunction.

P0353 is the DTC (Data Trouble Code) for "Ignition Coil C Primary/Secondary Circuit Malfunction", and it will require the use of a DVOM (Digital Volt/Ohm Meter) to test the coil, and you will need to check the resistance between the primary and secondary windings and they should be between 1500 and 50000 ohm's, and the resistance between the coil windings and ground should read infinity, but I have yet to see a coil that did not need to be replaced when that DTC pops up, and you should replace that coil, and also check to see if the spark plug is worn out, and if is worn out then replace them all along with any worn out or torn coil boots, a worn out spark plug will cause the coil to work harder and shorten the life of the coil.

The "C" coil is the third coil in the firing order, and if you have the 3.2 liter engine then it should be using a COP (Coil On/Over Plug) design and here is a diagram of the firing order and cylinder layout, and you can see that the "C" coil will be on the #3 cylinder and spark plug. (The second or middle spark plug on the right or passenger side of the engine).




The 2.2 liter engine uses separate coil packs, the "C" coil will be for the #4 cylinder and spark plug, and you should replace that coil pack. Also check the spark plugs for wear and the ignition wires should be replaced if they are over five years old and stock wires will usually have a date on them when they were manufactured and installed.

P0316 .... Engine Misfire Detected on Start-up (first 1000 Revolutions)

P0300b .. Random/Multiple Cylinder Misfire Detected

P0304b .. Cylinder 4 Misfire Detected

P0357 .. Ignition Coil G Primary/Secondary Circuit

P0353 .. Ignition Coil C Primary/Secondary Circuit

From codes you need new spark plus, Ignition Wires, and ignition coils

Check engine light. You will need a OBD II reader to retrieve the code.
Please let me know what you found.

Hi...
On your HUMMER . the CODE P0358. refer to Electrical problem.
Or malfuntion of the ignition coil. cylinder # 7.. The last one in Driver side. Start from Front to Back. The firing order is: Driver side, 1,3,5,7,. Passanger Side 2,4,6,8.
Primary circuit. Is the Spark Plug Wire.
Secondary circuit. Is the Electrical connector on the Ignition Coil.

Check the condition of the Spark plug, Spark plug Wires. and ignition coil. and the ignition coil Electrical connector.

OK.. I hope this help on your problem.
Thank you for use fixya.
