So when the truck acts up does it feel like the truck slows down and loads up or like the engine is stalling?
Is it worse when slowing down sometimes?
Ok. So if it seems more prominent on bumps that sounds like a wiring harness issue.
Have you had the PCM scanned for codes? That might tell us where the truck is losing communication.
That could be a fuel pump issue as well. It's really hard to say with it being random like that. Any idea what the code numbers were/are?
I saw that, but it could be the voltage to the fuel pump is somehow cutting out. A lean code (ie, p0174, p0172) would point to that.
Have you pulled any of the connectors at the PCM to look for corrosion or damaged pins? I would pull all of the PCM electrical connectors and look for signs of corrosion, water, dirt, or damage and then fill the connector with dielectric grease. Then drive it around and see if it will act up again.
There's got to be something loosing connection in there if that's the case.
Have you traced the wiring (brown wire) from the crank sensor all the way to the harness and looked for damage or a a short to ground?
If the transmission fluid is really low or if there is internal damage it will load up the converter and act like a manual transmission does when you stop but don't push the clutch in, but that normally only happens when decelerating.
It could be the throttle position sensor or pedal position sensor, but they will rarely make the engine stall. They usually just make it miss or skip and there is always a check engine light accompanying it.
The pedal position sensor is part of the pedal assembly. I've never seen one go bad without throwing a code though.
The ignition switch could be the issue, but normally other items cut out at the same time. Headlights, power windows, etc...
Here is the procedure for replacing the ignition switch. According to dodge it's plug and go, no programming required.
I just wanted to check whether you need any additional help.
