so i just replaced the fuel accumulator from bosch (not sure about the part number) and bosch coil as well but the problem still there when the car is hot , so in order to start it when hot or warm i have to turn ignition on , remove the air box and put my finger on something like a valve pass until i hear a beeping/buzzing noise and then it starts up immediately..
what i am missing?

This will then cause the fuel pump to run, developing fuel pressure just as you do manually by moving the sensor plate with your finger!

Then the sensor plate in the fuel distributor is not setup correctly, or there's an air leak. When cranking, there should be enough vacuum to move the sensor plate causing the fuel pump switch to open.
