2001 V2001 v70 2.4T Diagnostic help - CEM-1A5D / CEM-1A62

Situation:
I just had the timing belt / water pump changed and following the installed, the car does not start.

Here are the DTC codes:
== 14 modules responded to DTC query ===
BCM (Brake Control Module): No DTCs
CEM_H (Central Electronic Module): 2 DTCs
--> CEM-1A5D: Communication with the electronic throttle module (ETM). Signal missing.
--> CEM-1A62: Communication with the engine control module (ECM). Signal missing.
TCM (Transmission Control Module): No DTCs
CCM (Climate Control Module): No DTCs

CEM_L (Central Electronic Module): 2 DTCs
--> CEM-1A5D: Communication with the electronic throttle module (ETM). Signal missing.
--> CEM-1A62: Communication with the engine control module (ECM). Signal missing.
DDM (Driver Door Module): No DTCs
PDM (Passenger Door Module): No DTCs
REM (Rear Electronic Module): No DTCs

SWM_L (Steering Wheel Module): No DTCs
DIM (Driver Information Module): No DTCs

The car has been running with a autotech tune and the tune was "in" prior to the timing belt change.
There is spark however no injection.
Battery is fully charged and plugged in a battery charger
Car starts if gas is put in the throttle boddy / manifold.

My local volvo mechanic (been in the business for more than 20 years) does not understand what is this problem...

just read this post:

it seems that his issue was fixed by swapping the starter and engine relays

"By swapping the engine relay and starter relay over in the engine bay fuse box - MA1 and MA3, the dash messages have gone at IGN II and it has started first time!"

not sure if this applies to my situation though...

Any help would be appreciated
thanks
