Dodge po353 intermittant spark on cyl 5

You could have 3 different engines in that rig.
The firing order is 1-8-4-3-6-5-7-2 for most Dodge 8 cyl engines.
And the odd cylinders are on the driver side.
The small block engines ( 318 ) have the distributor in the back, and the big block engines ( 360 440 ) are in the front.
The rotor on the big blocks turn counterclockwise. The dist cap is usaully stamped with cyl 1 as a starting point.

Hi there:
The COP (Coil on Plug) ignition system is an individual coil for each cylinder that is controlled by the PCM (Powertrain Control Module). If an open or a short is detected in the driver circuit for coil number 3, a P0353 may set. Also, depending on the vehicle, the PCM may also shut down the fuel injector to the cylinder also.


If the engine is misfiring presently, stop the engine and disconnect the #3 coil wiring connector. Then start the engine and check for a driver signal to the #3 coil. Using a scope will give you a visual pattern to observe, but since most people don't have access to one there's an easier way. Use a Voltmeter in AC Hertz scale and see if there's a Hz reading of between 5 and 20 or so that indicates the driver is working. If there is a Hertz signal, then replace the #3 ignition coil. It's likely bad. If you don't detect any frequency signal from the PCM on the ignition coil driver circuit indicating the PCM is grounding/ungrounding the circuit (or there is no visible pattern on the scope if you have one) then leave the coil disconnected and check for DC voltage on the driver circuit at the ignition coil connector. If there is any significant voltage on that wire then there is a short to voltage somewhere. Find the short and repair it.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

check the ignition coil or coil pack of their resistance,
primary must have 1.0 ohm to 0.5 ohms(tolerable).
secondary are between 900 ohms to 12,000 ohms

A code P0300 may mean that one or more of the following has happened:

• Faulty spark plugs or wires
• Faulty coil (pack)
• Faulty oxygen sensor(s)
• Faulty fuel injector(s)
• Burned exhaust valve
• Faulty catalytic converter(s)
• Stuck/blocked EGR valve / passages
• Faulty camshaft position sensor
• Defective computer

CODE PO353 IGNITION COIL C PRIMARY SECONDARY CIRCUIT FAILURE MALFUNCTION.

mine does that too, somtimes im parked on as angle and it comes on. Sometimes i am driving down the highway and the light comes on. If you find out why let me know

Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !

My sincere apologies for the delayed response.
I am personally going back to answer your unanswered questions.
I have only been a free contributor to this site for the past 4-months.

I do not know if you still need this information, but I am going ahead and answering it anyway.

I'm not sure if you have the 2000 Dodge 1500 with the 3.9L (6-Cyl), 5.2L (8-Cyl), and 5.9L (8-Cyl) Engine; however I have included.

For the 3.9L (6-Cyl):
Firing Order:
1-6-5-4-3-2
Cylinders:
(back of engine)
6----------5
4----------3
2----------1
(front of engine)
Distributor:
(+).6...5
1...........4
...2....3..(+)-screw

For the 5.2L AND 5.9L:
Firing Order:
1-8-4-3-6-5-7-2
Cylinders:
(back of engine)
8...........7
6...........5
4...........3
2...........1
(front of engine)
Distributor:
.......(back)
.........3
....4........6..(+)
8...............5
(+)1........7
.........2

Again my apologies...

Let me know if this helped, or if you have any additional information or questions. Feel Free to contact me at FixYa.com!

the Wires Go Accordingly to prospective Terminals, So Sorry Unable to Send Pics through FixYa, A Formating Problem Exists
and they show on my end but not on your end this is TRUE and CORRECT To The BOOK other than the Lines from Coil to Spark Plug ENDS at CYLINDERS. Please dont Forget to RATE Me
Thank You And Happy Motoring!!

try replacing the coil, my 2.5 did the same thing, and after changing plugs,wires,distributor,rotor,rotor button . the last thing i repalced was the coil and i have not had an issue since. all work was done about 6 months ago.
