GM Crazy CAN! (No crank Equinox) - Part 2 -COMEBACK??

The shop installed a used ABS module on this 2008 Equinox, and STILL it will not crank over. WHAT DID I MISS? This turns out to be a huge learning opportunity about hidden variables when making a diagnosis. In the end, victory is achieved :) LAUNCH DIAGUN: https://www.amazon.com/dp/B072FHLYRY/... Enjoy! Ivan
