check engine light code says pcm car starts then cuts off PCM replaced july 2011 on 2005 Ford Escape

total break down july 2011, new pcm installed no problems since, check engine light came on Sat. so I took it to the dealership and the code was pcm again, they said there was no drivability issues, but the car didn't start today. It would turn over then immediatly turn off. After three tries it stayed on, but this seems like a drivability issue to me!
