My wife drove the car with an empty tank of gas, when we put some gas in there the car did not start up. After checking that the fuel filter, relays were in working order, I decided to get a new fuel pump and installed it but the car still will not start. The fuel gauge made a 360 turn and fell to the bottom of the dash. What can be wrong?

Recheck wiring to the fuel pump. It sounds like something may be wrong from the sending unit. Also, you need to check to see if there is any fuel pressure at the fuel rail to determine if the pump is working.

Spray the intake and see if it trys to start. Check the fuel pump fuse you may have blown it.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
