Recently purchased from private owner, ran fine for a bit then problems started to arise.
1. Pressure switch failed spurting at least one quart of oil upon lower front of engine. Replaced pressure switch.
2. Cracked overflow bottle causing overheating, replaced overflow bottle and thermostat (nightmare). Ran for a couple days.
3. Won't start, won't crank. Headlights are strong. When I turn the key forward dash lights up normal, airbag light flashes with theft system remains on but not flashing oil and battery light remains on without flashing, check engine light remains on but not flashing and brake light remains on. No chime sounds are to be heard upon key cycling. I replaced starter, and neutral safety switch. Still no cranking. Some switching sounds coming from under the hood. Shifter feels a lil shifty, in the sense that it's not shifting very smoothly from park to drive our any other gear. Pedal switch keeps popping from pedal.

Good morning,

The fact that the theft light does not go out after 10 seconds tells me the theft system is preventing the starter from working. Check the guide below for resetting the system and try it and see if it starts.

I also attached a wiring diagram for you to view. Check the neutral safety switch and make sure the connections are good and there are no damaged wires.
