I was driving my car to work and the fuel light came on. So when i got off work I put gas in and drove it for a few miles afterwards. When I shut the car off and got back in it later it started up fine and drove fine and then a few minutes later... it was like some one flipped a switch and the car died... So i thought it was the fuel pump... So I replaced the fuel pump and the car is still not getting any fuel to the fuel rail... and i still dont hear the fuel pump turning on???? any suggestions where to start... I checked all the fuses and relays and all seem to be working.
