Sounds like the earth has parted from the engine and it may have taken a few fuses with it.
An Auroelectrician should be able to fix it easily, subject to parts availability of course.
The oil light would come on because the engine stopped and there was no oil pressure.
Crankshaft Sensors come in various qualities. The ones make in China and Mexico have a history of failing and even being faulty at new. Always buy OEM quality, on a Plymouth, probably Delco.
Ideally you need an auto electrician with a pro grade scan tool. They come in qualities too. You can get one for $125 but the pro tech pays $5,000. The difference is astounding. As you have *multiple* misfires, I reckon your CPS is the issue or the connector to it..
