Check for spark, then check for fuel, if you have both, check the compression. If your missing fuel check the fuel filter or pump relay/fuse's. It could be a number of things but the 3 main necessities that a gas combustion engine needs to run is fuel, spark and compression, without 1 of those 3 the car will not run.
try replacing the distributor that is what mine did & i replaced fuel pump & throttle body position sensor and it still did the same thing would start so i replaced the distributor and now she runs GREAT & have had no problems out of it at all since then!!!
