While driving home from school, my oil pressure gauge fell to zero, I immediately turned off the engine and pulled to side of road and was towed home. I checked the oil and it was only 1/2 qt. Low. What is my problem>?

Check the oil pressure with a mechanical gauge if normal replace the oil pressure sending unit if abnormal could be oil pump/engine bearings.

I replaced the oil pressure sending unit and now it reads normal, however it turns over but won't start. Is there a reset switch or somenting I need to do?

There's no reset switch

Do below for No Start

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors-
