can an oil pump be the reason my 98 century wont run

you need fuel pressure, compression and fuel to run. start with basics.

no, oil pump will not cause this unless the motor will not turn

Check the battery first. In this heat, as in the dead of winter, car batteries can falter. Work your way up to the fuel pressure, check air filter which could be clogged with mice stuff or oil, and also you just might be low on gas.

If the engine will fire with a starting fluid sprayed into the air intake, but will not continue to run, check for fuel pump activation when the key is turned on but not to start. There should be a loud humming if you get by the passenger rear tire. If you don't hear the pump when the key is turned on, check the connector / plug that is located behind the passenger rear wheel. If you lie on your back, and slide under by the muffler, look up along the inside of the car body. You will see a connector that controls the fuel pump. Make sure it is seated and terminals are clean.
