What engine? What car? Like said, you posted in '92-'95.
Are all the plugs getting spark? Is the fuel pump priming? Is the battery fully charged? What is the color of the spark? Does it do it when cold? Warm? First thing in the morning? After driving and then returning after being in the store?
Details if you want help. You gave nothing to go off of that leads to any kind of direction. You need 3 things for a combustion engine to run: 1-Fuel, 2-spark, 3-air. Find out which one it isn't getting and go from there.
If you can't provide good details so those that aren't there with the car trying to help can give the right direction to go in, or if you can't perform basic troubleshooting to figure this out, it might be best to have the car looked at by a local mechanic.
This could be anything from a bad main relay, to poor maintenance, to bad gas, to low gas, to bad ignition timing, to flooding it by pumping the gas (this isn't an old carb'd muscle car), to even a bad/low battery, or anything in between.
