Truck dies while driving then won't start right away
I had the same problem on my V8 Ram Van. I wiggled the right most connector and it worked for a few days. Then the "no bus" - no start message; Wiggled again - okay for a few days...... Eventually figured out that there is a bad connector in the PCM. Ordered a new one from Auto Computer Exchange - installed it - everything works 100% again
The crank sensor, the coil & most sensors are packed in hard epoxy resin. When it is all totally cooled off, if it starts right up then poops out after warming up, then consider that anything with a hairline crack where you cant see it may spread open as it expands with heat causing it to run no more, then after it cools off & contracts again, the connections are back to where they need to be to fire off allowing it to start & run. This is really common on GM coil packs - they can bench test fine while cool, but get warm on the engine causing this exact issue. The PCM would be the last thing I would suspect. Crank sensor & ignition coil are my 2 top choices for the real issue.
I swapped both those out on mine and it still did it. I knew it had to be something with the PCM from the get go bc it wasn't throwing a code and none of my gauges were working until the truck started back up.
I literally just went through all this funness with my truck. im no tech or anything im just going by what ive done.. check ur battery, check ur alternator. a bad battery and some dumbness were what was wrong with mine.
Sorry, forgot about this thread. It was the TPS sensor. I started wiggling wires under the hood and when I wiggled the wires to the TPS sensor it started to die. Replaced the sensor and fixed the issue. I also posted a vid on YouTube for anyone else that may have difficulty replacing it.
