2001 Chevy Prizm parked it because it had a tap and needed an oil pump now why won't it start at all?

If your 2001 Chevy Prizm won't start after parking it due to a tapping noise and needing an oil pump, it could be due to several reasons. The tapping noise might indicate a lack of lubrication, leading to engine damage or failure. If the oil pump is malfunctioning, it may not be circulating oil properly, causing the engine to seize. Additionally, if the battery is dead or there are issues with the starter or ignition system, that could also prevent the car from starting.
