I have the same problem. The dealer has installed a new throtttle body, then a new ECM. I STILL have the same problem. The dealer has no ideas and now wants to charge me to see if my valve seals are leaking. Sure, after $2,400 I'm going to let you pull the top of the engine off to check my valve seals.
One mechanic (non-Cadillac) feels the battery ground wire is corroded and should be replaced so that's my next step.

Battery voltage is definitely and issue. Charge your battery and have it tested before condemning the starter.

If the ECM was replaced properly it have no efffect on the engine starting. If the starter is turning the engine over then it's doing all it was designed for. I think I would get it out of that shop. I smell a rat over the internhet.
