When you say "turn over", what do you mean? It means starter not cranking to me and that would have nothing to do with coil or opti.

If you mean it cranks, but does not start, check for spark. There are some tests for coil and opti on my Tech Page.

Listen to make sure the fuel pump is running when you first turn the key to the "on" position. Check your fuel pump fuse to see if it's blown. Sounds like you're not getting spark or fuel.
