Smell the oil - if it has a fuel odor, you may have a leaky injector flooding its cylinder - the fuel is running down into the oil pan. This can damage the cylinder because the rings would not be properly lubricated in this situation, so don't put off fixing it. This may also cause run-on when you turn off the ignition - the unwanted fuel explodes at full compression. If your check engine light is on, you may find it helpful to read out the error message(s) - 1995 and newer computers can often identify which cylinder has problems.
Some or most cases the throttle body has a air charge temp sensor built on it or your throttle positioning sensor is going bad. Most engines that size operating oil psi is 40to 60 depending on the type and weight.

your fuel pump should cycle on until the proper fuel pressure is achieved then it should shut off

Anti theft system. You might have a door lock causing the anti theft system to kick in. (thinking its being stolen.)

I suspect you have had an oil pump failure. To get at the rotory gear oil pump you will have to drop the oil pan. After you take the pan off, ( having drained the oil the oil pump is what the oil pick up line leads into. That pick up assy. is a round shaped disc with a screen inside it. Clean the screen first then the oil pump. Install new oil pan gasket on reassembly. Hope that helps you. Please let me know.
Hopefully the engine was not damaged when the pump broke. If it was you may need a complete engine rebuild, MAYBE.

Fuel pressure is a little low, check the pressure regulator, and the fuel filter
