Hello and welcome! My name isCustomerand I can assist you with your question. Was there any codes in the computer when the mechanic plugged into it with the diagnostic machine? Have you checked for spark and fuel when this occurs?

No Codes

You might just have a bad fuel pump. Was the fuel pressure checked when this happens?

Customer: replied 9 months ago.
the fuel pump was replaced right away, fuel pressure was check and of course all ok, but like I said intermittent problem
Expert:  AMEDEE replied 9 months ago.

Provided the engine has spark, the engine is either the engine is missing fuel pressure or injector pulse. So your going to need to check the fuel pressure WHEN this condition occurs. The fuel pump may be losing power for some reason preventing it from coming on. For the injector pulse, you would need to use a tool called a noid light so see if the injectors are getting a signal to pulse fuel into the cylinder when cranking when this no start condition occurs.
