Default Wont start, no green ligth, no communication

Hi, i need some help thanks
2008 crv 2.4
Cranks,but dont start
All relays and fuses are in good condition
All grounds are at 0.0 omhs
The green key ligth never go on when i switch the inginiton. Dont flash, no nothing of green key
The PRND21 ligths on dash dont go on (dont matters the position of the shift ****)
All other ligths in the dash are fine
Scanner cant communicate with pcm
All the pins of the pcm conectors have 12v and grounds where needed
Even the imobilizer have the correct grounds and 12v supply in correct order

The same for the obd conector
All the relays where tested ....all the fuses
Are fine,
I try with a diferent pcm and is the same no green light
no communication whit scanner







I test the original pcm in another crv and the green light start blinking
and the PRND21 ligths on dash got power , and i was abble to read the pcm, that make me think pcm is fine
Somebody maby have clue thanks
Forgive my bad english,

Did anyone figure anything out on this? My 2008 CRV had the exact same symptoms plus my shifter will not unlock.

Anybody?
