What will cause the fuel not to leaves the high pressure pump to injectors

Thanks, however, a diagnostic test was done and base on the results these parts were replaced. Now I am still at a cross road therefore it would be most helpful if you can indicate any possible thing(s) which May contribute to the car still not starting.

I’m sorry to say that nothing I could possibly guess at here replace is having a diagnostic tool connected to your vehicle while the problem is occurring. In that case, you don’t have to guess at anything. It’s all right in front of you. I’m sorry we can’t help here further.
