The code that I pulled back was 23 - which would be No1 Cylinder Top dead Center sensor -

It's possible I misread the code and it was actually 22 - my volt meter gave me two long 12v. spikes then two short 12v spikes then a short pause and another short 12v spike before going through the cycle again. Is it possible this is actually 22? which would be crank angle position sensor? I'm pretty sure I read it correctly as code 23 but i'm curious as to why the three short spikes weren't evenly spaced apart before going back to the long spikes for the first digit of the code, but in any case not sure what to do next. I'm not familiar with the TDC sensor or where it is and the issue is still occurring.

ohh - also I read the code by putting my positive on what I believe to be the #1 pin (as I'm looking straight at the diagnostic harness, the pin farthest to the driver side on the bottom) and instead of putting my negative on the opposite ground pin on the harness, i put it on a known good ground on the car chassis (i used a ground spot under the glove box that's used for the one of the ECM wires) - when I tried my positive to the 1 terminal and the ground terminal on the top row far right, it didn't give me any readable voltage pattern.
