Acts like it doesn't want to start but eventually does. Gas light stays on gauge says empty when full but sometimes will say full.

Good afternoon,

When you turn the key to the on position can you hear the fuel pump run?

I would start by testing the fuel pressure to be sure the pump is working correctly.

As far as the fuel light, that is usually a bad sender unit.

I attached a wiring diagram for you if the pump does not work. You would need a test light for some testing.
