If you've got a no-start situation, the ECU can easily tell you if it's the CPS, no need to use a meter or disconnect anything. Refer to OBD DTM 2 on port 2 in the FAQ here. If that test passes then
pull the AMM connector and attempt to start in limp home mode, which would suggest a cooked AMM if it now starts and runs, albeit a little rough and hesitant at higher rpms. From there you would then proceed to try isolating it to the fuel or ignition side.
