Wouldn't the code reader pickup the issue if the CPS sensor was bad? There are no codes at all.
I've seen a bad CPS give no codes and many false codes. There is no computer logic checking the CPS cycle. There is also no computer logic or sensors checking fuel pressure. It's not a guarantee that is the cause of your problem, but it's a possibility.

I purchased my 06 Crossfire with 4,700 miles on it last year. During my test drive there were no problems. Later I found that at fast exceleration hitting consistently around 3,000 RPM the engine would stop running, and I would have to do a restart. Putting a scanner on it I saw multiple very strange condition codes which didn't make sense related to the engine dying. I don't recall what the codes were, and it does not matter now. Given my experience, and knowing the CPS would cause the engine not to run, I decided to replace it as I had two spares. To my surprise, with the car having so few miles (but it was 14 years old), I found the CPS in the car had been replaced, and with a non Bosch unit. It was easy to see that as it was a light grey color. I put in the Bosch CPS and the problem was solved.
