The Hybrid system fools a lot of people in the same exact manner. The engine is actually cranked via a dampener assembly (The Two Mode 2ML70 trans uses a dampener in place of a torque converter)
The engine is cranked by one of the two transmission interior electric motors at a high rpm and what you are seeing is just the engine being turned over at around 700 to 800 rpm it NEVER actually starts. You have a engine problem probably just a bad fuel pump etc. Now that you know what to look for it should be an easy fix.
