Stopped running on 3 cylinders

Hi some time since last post, spent 12 months getting new injectors dismantle intake etc and carbon clean (and buying camera to check valves closed)
Since which has run fine for 6 months. However last week in for Service all I fine until finished standing ticking over suddenly stopped firing on cylinders 2,3, and 4 run's on1 for a while then dies. Will start on number 1 and run but will be obviously needed to be stopped.
Initial reaction it was use diagnostic which showed loads of Cannot Communicate errors So ECU failure we thought.
But when started again diagnostic machine shows no errors????? But still only number 1 runs
Many reasons why just one cylinder may fail but 3 at once, any ideas
Mechanic is going to pressure test cylinders before moving back to getting ECU off and sent for testing
Update No compression on the 3 dead cylinders
