After checking wires this afternoon, I have 5vdc from the ECU to the TPS and Hall sender. All other sensors off the ECU have 12vdc. Both ECU's have the same voltages. I don't have another mkIII handy, but the one I was able to check did have 12vdc at the Hall sender. So, I still think have an ECU problem.
But, it has another problem. I checked cylinders 1&4 and they only have 30#'s compression. So, either the timing jumped , the cylinders got washed down with gas or something else mechanical happenned.
I guess it dragged down to the shop and some midnight oil gets burned.
