My stupid 1992 Buick Century

Our belt broke as we were driving, we drove another three blocks and parked (it was - 20 C or colder at the time). The car was left running, and I got out to take a look under the hood, there was anti-freeze and water on the top of the engine and down the side a bit. As I was looking at this, the car started sputtering like it was running out of gas (which I think it actually did), and stalled. We went and got a new belt and replaced the broken one, charged the battery, put more gas in the car, and now it will turn over, but there doesn't seem to be any spark. Any suggestions of why there is no spark? We have checked the plugs and wires, and fuses. We have tried to test the crank sensor, but can't get at it.
