Changed Oil Pressure Sensor- Now Fails to Start

[riegs]

Hey there!
Any advice or tips would be appreciated.
Changed out my oil pressure sensor because it was leaking real bad. Got a new one from part source and swapped it out. Now she won't even turn over. I turn the key and i just hear a click come from somewhere in my dash. It's a 1.6L 2001 protege.

I say "coincidence". First, check starting voltage at your battery. It shouldn't drop below 12V or so. If it does, charge the battery until fully charged. If you can't test it, take it out and bring it to an auto parts store. They can load-test it after they fully charge it.
Your battery may need to be replaced.

Oil pressure sender is not required for the car to start or run. Maybe you knocked a wire off of the starter or alternator?
