What Do I Need To Do? I Have Changed The Spark Plugs And Fuel Filter. That Wasn't It. It Sounds As Though It Is Not Getting Any Gas. What Do I Need To Check Next. Anyone Help A Sista Out!!

Check for fuel pressure... also get somebody to sit in the car. With the car off, lay under the car with your ear by the fuel tank... get them to turn the key to the on position and listen for the whir of the fuel pump. If you dont hear it, check the fuel pump relay by swapping another relay. If you still dont hear the pump, replace pump.

If the fuel pump is operating, you'll still need to check fuel pressure and compare to specs.
Finally, new plugs are good, but they need a spark to work, so make sure you have spark at the plugs.

What engine in the car and how many miles or kilometers are on it? Is it throttle body fuel injection, or mulitport FI?

First check for lose of spark or fuel.
Do you have good spark to all cylinders when cranking.
Good fuel pressure?
Does it start and run 30 seconds and shut off or just no start?
Any security or check engine lights on?\
Any codes stored in PCM?
