Open the hood if it says efiohc or single cam on the valve cover then it is a sc1 if it says dohc or twin cam than it is an sc2

if you have high resistance in secondary ign. system (plug wires, ign.coil) this will cause this code to set. make sure you are using a high quality spark plug wire set. not from autozone!!! and denso non platinum tipped spark plugs. also use a diaelectric grease on plug wires to keep moisture out.
SOURCE: fuel injectors don't work on 1994 Saturn sc2
There is a (#1 Ignition Fuse) located in the under hood fuse box. Remove the fuse to make sure it is not blown. If the fuse is good we will have to check for injector pulse. Let me know if you have a 12 volt test light and you will need a "noid" light to figure out if the ECM is driving the injectors.
Let me know.

Try replacing the belt tensioner. Comes out easily, once you figure out access to it. Remove inspection panel inside front passenger side wheel well. Tensioner is right there, two bolts. If the spring gets weak, the belt will squeak.

Sounds like the the Bendix is bad in the starter, which pushes out the drive gear to engage the flywheel. You'll need to replace the Bendix or the starter. It's a bit tough to get to the starter, it is underneath the intake manifold.
