Piloto,

You'll need to go through the standard procedure for diagnosis -- while it changes slightly from car to car (and is easier on older cars without computers,) the principles are the same:

Basically, the car only needs two things -- fuel and spark.

If you turn the key and the car cranks and cranks on the starter with nothing, simply take out one of the spark plugs and see if it has unburned fuel on it. Also with the plug wire attached, ground it to the block while another person cranks the starter. It should spark. If it doesn't, you have a spark issue, which means a bad wire to the coil or distributor, a bad coil, a bad fuse. If you have a multimeter, you can test between the starter and the spark plugs to find where the power is lost.

If you have spark at the plugs, you have a fuel issue. Could be a blocked fuel line, fuel filter or fuel pump. Fuel pumps also go bad. You can have a shop run a fuel pressure test.
