98 Cavalier won't turn over It tries to but doesn't It makes a feeble little rev but does not come close to catching Interior and exterior lights work turn signals work but won't start?

Things to check: Ensure battery is fully charged; check for corrosion on the battery terminal(s); check for loose battery/starter cable. If the cables are clean and it good condition and the starter still makes "a feeble little rev", the armature bushings are probably worn and the starter is "dragging" and not spinning fast enough to start the engine. This condition is repairable, but it might be wiser to replace the starter since "dragging" can also cause other damage to the starter. When you remove the starter (and before you buy another) have it checked (usually free) at the auto parts store.
