So the past few months if i let my gas gauge reach about 1/2 way my car starts to act up. Like if im coming down a hill to a stop i have to tap brake/gas/brake/gas or else if i dont give it enough fuel itll stall out, or even if i have to stop to fast. I never has this issue when i have anything above 1/2 tank, and the lower it gets the worse it gets to sometimes loosing throttle completely. Well i pulled into my driveway the other night and i just let it die, cuz i was turning it off anyways. I went to start it the next morning and it wont start, i get 40psi of fuel as to the normal 60psi. The car tries to turn over but it wont get enough fuel to start it. I even went out and got fuel in a can and filled it to about 3/4 tank. It hasnt been this bad before, i dont know what to do..
