I connected jumper cables from engine to chases and No luck. That rules out the ground straps as the cause of no crank. So I will scan for codes to see if 80: DME- EWS transmission parity code is back. If so I will run the DME - EWS alignment function again. Only this time I will turn on terminal 15 ignition then terminal 50 Crank when prompted. I am hoping the old tired battetry with 11.5v maybe caused the DME and EWS to fall out of synchronization. Fingers crossed. As I mentioned. The battery was replaced 2 months back.
