starting problem
 

We just replaced the alternator, alternator belt, power steering belt, A/C belt, spark plugs, and the air and air pump filters and did an oil change and replaced a broken radiator hose and put new coolant in it. After all of that we where able to start the car 3 times, and then it wouldnt start. When you turn the key all lights come on and the car turns but will not start. I was driving this car on a regular basis until the radiator hose busted a little over a week ago, when that happened we desided to do some other things that needed done while we where working on it. We checked the fuses under the dash and all of them look good. I am at a loss. Any ideas? It is a 1982 928.
