2005 Saturn Ion 2.2 no crank. Car ran into shop with low power, replaced pedal sensor, car ran but rough idle. Found bad wire between pedal sensor and Ecm, upon repair, discovered c1 connector had multiple bad connections. Repaired with used part, problem escalated to no crank and multiple communication codes Replaced ecm with used, still no crank but only code is ckp.
Trying to decipher the wiring, run/ crank ground switch is fed by ignition bus. Can anyone help me with finding the problem with this?

I wanted to post back and say that i found a loose connection at c1 right after posting this and ended up with the original ecm installed. Car started with no codes present.

Nice! B)

By loose connection, I figure you mean a spread female pin? Do you think someone was there improperly probing before you, or did it spread on its own?
