Hi, this is Bo, an auto expert on RepairPal's Car Genius team! When an engine sounds like it wants to start but just won't commit it's usually a fuel or spark problem rather than a mechanical one. A weak fuel pump that can crank the engine but can't deliver enough pressure to actually fire it up is a common culprit. A failing crankshaft position sensor is another strong suspect since without a proper signal the engine simply won't know when to fire. A quick check for codes, fuel pressure and spark would point you in the right direction pretty quickly without throwing parts at it.
