Hi guys
I have had this problem for a long time. It was initially a bad sealing fuel cap leading to the cell signal which was misdiagonised as a bad fuel pump. The mazda people went and replaced my fuel pump and they managed to screw up my car.
After that, the fuel will not flow into the fuel tank from the filling neck unless much time is given, so it takes 10 minutes to fuel up the tank as the gas slowly enters the tank.

what could be causing this?? what do you guy thinks? THANKS

 

I think there is a one way valve in the fuel filler line...must be stuck partly closed

 

googled around and it seems to be the only cause of fuel not entering in most vehicles, and if it is broken, I will need a few fuel tank. HAHAHAH
LOL WTF

sigh...
