What does it mean when the oil light and couple days later a wrench came on dash

So it turned over ( cranked ) slow ? Bad wiring or cheap starter , When wires get warm it creates more resistance , more resistance means more heat , the problem may be at the batt terminals or a voltage drop from a bad batt/starter cable . If your oil level is good then that car may have seen better days , If it made it this long you're lucky and I wouldn't put a bunch of money into it to fix it ..

Check the battery voltage , should be 12.5V, and check the oil level, you might just be low. Add till full.
