I have a 2001 dodge ram 1500 5.9 auto 4x4 quad cab. In the last month the truck suddenly shuts off while driving 3 times. when I try and restart the motor turns but it will not start and I get a "no bus" code on the odometer. After multiple attempts (5-10 min) it turns on.The dealer said they can't find anything wrong and It could be the pcm (they need to check the truck when it's dead). I'v looked into replacing the pcm, I'v been told it has to be flashed with the car & I'v been told by pcm rebuilders that if you give them the vin # they will send you a flashed unit.
Is the pcm the problem or should I look somewhere else? Can the pcm be flashed off the car?
