Hmmmmm evo sad sam malo probao da progooglam i nesto sam isacackao, izgleda da to tako treba da se desava i da se po otvaranju vrata pumpa aktivira i stvara neku vrstu predpritiska u sistemu, to se desava samo kada auto stoji neko duze vreme, tj kada nema pritiska u sistemu...
"It won't prime if the fuel system is already pressurized. If the car sits for a while the pump will come on, but if you just turned off the car and open the door, or close it and then open it, the pump won't come on."

"Questions to help diagnose:
1) when you open the driver door, do you hear the buzzing noise from under the car? If you hear that, your fuel pump is working. Your problem is not the fuel pump, fuel pump relay, or fuel pump fuse. Stop reading this thread, it does not apply to you.
If you do not hear the buzzing noise when you open the driver door, the fuel pump is not priming."
