Okay, so when you jump start it the engine cranks and cranks real fast but the engine doesn't run, is that right?
If that's right, then you need to check for spark and check for fuel. Spark can be checked by buying yourself an inexpensive spark tester at Kragen or Autozone (high voltage ignition systems can be dangerous for some people if they get shocked). No spark? Probably an ignition module failure of some type.
For testing fuel, one easy way would be to squirt some starter fluid into the intake manifold (NOT WITH THE ENGINE CRANKING!!!) and then try to start the engine. If it momentarily runs, then you know you don't have a spark problem but rather a fuel delivery problem. In that case, one thing you can do is check the fuel pump fuse and/or fuel pump relay fuse and / or fuel pump relay itself.
If none of that works, it's probably time to haul 'er into a shop.
