2013 ram 1500 hemi stalls randomly, then fires right back up. Sets codes for every ignition coil insufficient ionization p2302 p2305, p2308, p2311, p2314, p2317, p2320, p2323. Spark plugs have been replaced, coils looked good upon inspection, asd relay has been replaced, pcm replaced, it has push button start, not throwing any codes for can or crank sensors, any input would be appreciated.

Was this the same condition that caused you to replace those parts? As in, were you having these exact same codes/symptons, replaced the parts and the same symptoms persist?

Also, were all of these parts replaced with OEM parts, or aftermarket parts?

Are the ignition coils OEM or are they aftermarket coils. If your not sure, post a pic of them.

Where did you buy the spark plugs?

Here is the wiring diagram for your ignition system. If you have verified that the coils, spark plugs and new PCM are known good OEM parts and not cheap aftermarket junk from Amazon or ebay, then break out your multimeter and make sure the ignition circuits are good between the PCM connector and coil connectors.

Here is the diagram with wire colors, connector and pin numbers:

when you say "coils looked good upon inspection", what do you mean? The coils cant be disassembled so you aren't likely to have been able to inspect the primary and secondary coil windings. Did you install them on another truck and make sure they run fine on the 2nd truck? Because a visual inspection tells you very little.

Unless they are some bright neon color and have some flashy name and logo on them, in which case, there's a high probability that they ARE the problem.

Thanks for the reply. Yes this was the condition that lead me to replace those parts, I used oe plugs, and a used pcm from a known good vehicle. I have tested the wiring and everything checks out fine that’s why I replaced the pcm. Many times it will stall without throwing codes, but when it does set codes that’s what I get. The coils are original. And it’s very random, after replacing the spark plugs it was good for one week then came back, then it might be good for a day or two then stall randomly. I’ve also done a throttle body service. Thank you

Ok.

The ignition coil circuit typically has continuous power and is controlled by the PCM grounding each one at the right time, to fire the coil.

Have you inspected the ground cables and straps.

Intermittent electrical issues are frequently caused by a poor ground connection somewhere.

Is Innisfill, Ontario one of those places where its always cold, wet, and they salt the roads alot.

Because corrosion at the grounds, wiring connectors and the connectors on the underside of the TIPM seem to be a very common problem in places like that?

It sounds like you've checked the PCM/coil side of the circuit. If you havn't already, check the TIPM/ASD to coil side of the circuit.

I will have to double check them all

It sounds like a spark issue, at the center of spark is the battery, so how old is battery? Have to inspected terminals and ground?

Usually if it is an ignition issue there wont be codes, what I would do it keep running codes. Did the codes only pop up once?

Yep it gets cold in the winter, and they do salt the roads a lot. I have checked under the tipm and doesn’t seem to be corroded. I will double check though, and check the grounds also. According to the schematic, only the asd circuit and the pcm are the only things every ignition coil have in common. I’m just wondering if something else causes the stall and the pcm sets the codes because of the stall causing insufficient ionization

The codes only set once in a while, it will stall multiple times without setting any codes. The battery is good terminals are clean with no corrosion

how old is the battery?

Something is causing the coils to not get proper juice. Does this happen mostly on first start or at anytime of the day? Even a warm engine after 30 miles still does this?

Not sure exactly how old the battery is, but it tests good with a good battery tester. It’s happens randomly. It can happen right after startup, it can be good for a few days then stall randomly, but it always fires right back up with no hesitation, and when it’s running it runs perfect, no misfires etc

So if ram forum proved anything over the years, battery tests are useless. The issue is capacity. Usually the battery date is on it, but if you think it is over 5 years old, way time due. Added to the fact then hemi needs a lot of cca. If you felt you needed a battery based on this info, there is a punchers chance it can solve lack of juice issues and would be the cheapest fix if it worked. Cold regions are the death nail for cca as you can see. You get great battery life and it will test good, but you could be down 60% capacity.

Next time you have the coils off,pull the boots and check the spring inside the boot and contact point over for corrosion.The boots just pull off with a good tug and twist. Doubt it has anything to do with your issues,but your coils are probably due for a cleaning under the boots

I am having the exact same issue with the same truck: 2013 Ram 1500 4wd Sport 5.7. It started stalling randomly, then it would fire right back up, and I'd be on my way. The other day it cut out and wouldn't fire back up; it just cranked, so I had it towed back to the house.

I haven't had a chance to look at it until today and of course, it fired up and idled fine for a while in the driveway and then finally died. It threw codes for every ignition coil insufficient ionization p2302 p2305, p2308, p2311, p2314, p2317, p2320, p2323 so I reset the codes, unhooked the battery for a while then hooked it back up and it started just fine so I scanned it while it was running and it was throwing the same codes while running before it finally died again.

I have the service manual and wiring diagrams printed out, just curious where to start and if Highboost got it figured out. I haven't replaced anything yet but my first thought was same as highboost, just replace the PCM since it's one of the two things that all 8 coils have in common.

Any help will be much appreciated, thanks!

Ignition capacitor? Could it be an issue?

@Ken226, Where are you getting your drawings and diagrams?

Before taking anything apart or buying any parts, make sure you start with a tested, known good battery.

This is the time of year where weak batteries start to cause problems, and most testers wont show a bad cell. False good tests are super common with parts store digital testers.

Use an old, toaster style tester that actually puts the battery under load, like the cheap harbor freight one.

Thanks for the response Ken226!

New battery installed in July, but I ran to HF anyhow. Battery tested good...

I'm pretty capable, but this one has me stumped...
