5.9 ram PO340 code
#21
I have over 250,000 on one vehicel, and have had that many on 4 other vehicles, and cannot count how many vehicles I put over 150,000.....and I have never had a PCM go bad. Sometimes mechanics and owners rush right to PCM change just to find out that it was not the problem. Lots of money wasted. PCM can go bad, but if you search, you will see more threads where PCM was replaced and problem persisted.
Need to check injector pulse. And if that is good, pull injectors and clean. Crud may have them plugged up. I read a thread the other day where someone referenced fuel rails rusting and causing problems. Fuel, spark, and timing......all gotta be good to run.
If you do decide to swap PCM, I would suggest JY (same model) and maybe coil for grins. At least you will be able to verify for less money.
