I do not have experience with this, but older cars had inertia switches that disable the fuel pump and that had to be reset. Did you check for inertia switches?
Perhaps those lateral acceleration sensors are one time use items, and have to be replaced as well. I just don't see why you have PCM communication errors or why they would prevent the car from starting.
