My 07 DTS would turn over well but not start. It almost fired, stumbled and died. No check engine light, No code at Autozone. Replaced fuel pump and purge valve and that didn't help. Replaced the fuel pump relay under the back seat. The world is good again.

It's good you replaced both the fuel pump and relay. A bad pump will burn out the relay melting the base in worst case examples.
