Car start but dies immediately

Question

Great work you guys are doing. I have a nissan maxima 2000 with no scan code but when i start it,  it start and dies immediately. If i dont want it to die,  then i have to put gas (by pressing pedal for 5-8 secs to stable.
I have tried to change fuel pump,  clean the injector and even change air flow meter no luck. Please assist.

Answer 1

This is with the fuel pump , on the fuel pump there is a return line that has a o ring on the return , this tends to pop out and lower the fuel pressure volume, this is the reason why it is important to use top line fuel pumps,

If you can safely clamp down the fuel return line at the engine area. to rule that out ,  if it runs better suspect the fuel pressure regulator. Ive seen these problem before especially if you are using a airtex fuel pump module
