CHeck your relay in your center console. No starting situatio can be a result of a couple of things.
1. If the car cranks and doesn't start than its a no fuel or spart situation
2. Car doesn't even crank just sits there but dash lights come on and hear the fuel pump its either a bad connection to the starter, relay or the starter itself.
Those are the most common kinds. I pulled my starter out when I had this no crank problem and the starter was spinning fine regardless. My problem was the car would start sometimes and sometimes nothing just dash lights come on and hear the fuel pump (That means the clutch switch is working). So they I ruled it out to either bad relay that doesn't want to close sometimes or bad connection to starter.
