My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
If the cylinder wall was damaged in the cylinder the piston damaged was in this will cause low compression and misfire as well as smoke from engine oil burning.If you did not have the cylinder wall checked before the piston was replaced this can cause this here.

hi pete i am told that cylinders 3 and 4 are not firing we changed the #1 piston which is working we slackened the diesil lines to cylinders individually but cylinders # ***** and #2 are firing but when we reached #3 and #4 the engine died

Inspect electrical connections and wiring in the area of repair that was done to see if you locate any faults needing corrected.In some cases when a major repair like this has been done this can lead to loose or damaged electrical connections or components needing repaired or replaced.
It is possible the injectors for these cylinders have failed causing this issue as well needing replaced.I have seen this occur before even after a repair like this here and had to replace them.

A flashing check engine light usually means the engine computer has detected an engine misfire.I would still have the fuel injectors tested to see if any of these are at fault needing replaced to correct this issue.
