1996 Chevrolet Camaro having trouble running

Well I recently bought the car I knew what was wrong with it (distributor) so I bought a new one. After installing it I decided to buy a new coil and fuel pump as well just to make sure. It started to work with the new distributor it was running for about 4 days and now it wont start any more, before I bought the car it was garaged for almost 4 years. I need help on trying to figure out what the problem is, is it actually the distributor or is it anything else? Please help. Thanks!
