Angry 2003 montero limited 3.8L very hard to start

Hi all montero! I have 2003 montero limited 3.8L.It very hard to starts may be one minute for key rotation then starts if I give gas.When engine started the idling is very good and no fluctuation.
I did so far:
-new temperature sensor(every 2)
-new battery
-new starter
-new generator
-new fuel pump
-new fuel pump filter
-new fuel regulator
-new PVC valve
-new spark plug(6)
-injector clean(check fine every 6)
-fuel system pressure: 0 bar when ignition on
-fuel system pressure: 3.2bar (when engine works)
-throttle clean
-Mass Air Flow Sensor(MAF) clean
-EGR valve clean
-engine pass with scaner(Autel MaxiDiag Elite MD802)
-I put over the first fuel pump relay to the second fuel pump relay's space, than I put the second relay to the first relay's space. The car does the same as before.
HELP! What more can I do? Sorry for my small English language knowledge.
I'm waiting for answers and thank you forward.

In my 2003 Montero Limited this symptom was a faulty fuel pump.

Tee pump sounded like it was working, smelled fuel at the engine like it was working. But it had become weak and it wasn't until I replaced the fuel pump that I could start it up again.

Now all is well... for now.
