Just a quick video, for those of you dealing with the notorious Dodge JTEC PCM "No bus" issues. My 99 5.2 has this issue. All the typical sensors have been replaced, but it still has the stall, no start issue. Typically only happens once the engine is up to operating temp and it's hot out. So, if nothing else has worked, try doing this. It pretty much narrows it down to the PCM. There are several "band aid" temporary fixes, but in the end, the PCM needs to be rebuilt or replaced.

I have this problem but not gauges and I have the 5vdc going to the sensors, and the sensors are putting out pulses to the PCM, good ASD relay as well, but the pcm is not turning it on, so I'm thinking it's probably the PCM too. Thanks for sharing. Best Wishes & Blessings. Keith Noneya

I currently have this exact same issue on my 1999 , 3.9L Dakota and am very tired of being randomly stranded. I have changed the PCM this time and it did not resolve the problem. I have had this issue before a few years ago and had to replace the PCM and it did fix the issue. I am replacing the smaller items that may be causing this such as cap and rotor button, wires and ignition coil and maybe the crank sensor. It may even be the wiring harness. If i do replace these and it does not fix the problem i may exchange the PCM again as i suspect that may still be the issue......... it happens ....not every part is good out of the box.....especially a remanufactured PCM vendor.

Bro I have same problem. What the problem it's pcm or sensor crank?

@timschannel910 2 года назад

Was it the pcm. Did you get it fixed. I have a 2001 dodge ram v8 doing the same thing.

@jonanderson4755 2 года назад

Yes, it was the PCM. I ordered a rebuilt one from Ebay and luckily it worked. Unfortunately buying a rebuilt PCM can be a 50/50 chance on it being truly "rebuilt/refurbished". Mine came from Auto comp technologies on Ebay.

You ever fix the issue? I’ve had my truck sitting, because I work down back roads and it’s left me stranded once because of this. I’m waiting till tax time and buy ya new computer.
