1992 Chevrolet Lumina Questions

OIl light keeps coming on and it doesn't need oilps

I was needing to know how to tighten the cigarette lighter in my 92 Chevy Lumina

Just purchased a new battery for lumina and it cannot pass MARTA. My camry can but I need a new battery.

The temperature gauge spikes within 5 minutes of driving. But after I sit for 15 min and start again I kind of Gun IT and the gauge would go back to normal and drive perfect, just the low coolant light would stay on but No service engine light has ever come on and I checked to make sure the CE light is working. Now the problems worse because it started stalling or almost dies when I try to take off but it then dies when I stop at stop lighting stalls and sometimes starts but sometimes It won't and I have to wait 15 minutes. I checked to make sure the computer is working by turning they key and checking the dash lights. I replaced Coolant Temp Sensor And Temp sending unit/ switch, the Thermostat also flushed radiator and bled the system. I can try other things but wanted to seek help first. Sorry so long I try to be descriptive.

Don't see any other bolts am I missing something?

car smells of gas and sometime stalls at a stop

my cars sometimes and smells like gasoline

Is this normal or an indication of the oil pump going bad?

my power steering in my car started leaking recently, and i replaced the pump and resivour. it seemed to hold for a few days.
but now it is leaking again. nothing massive, just a small amount on the ground.
could it be the lines leaking? if so, what do i need to replace it?

Speedo was erratic for a while before it quit entirely. It would read higher and lower than the car was going. Torn between buying a speed sensor or a new (used) speedo on Ebay. Is there a way to diagnose the speedometer or the sensor before purchasing?

stalling out and hard to restart. the engine still smells like gas.

it will restart, when i put it in drive it stalls again,usually after five minutes it will start and drive again, the car had not been driven for 8 yrs only occasional starting it had a quarter tank of old gas i put in gas treatment& fuel injection cleaner and added twenty dollars in gas .It has had a tune up ,fuel injectors cleaned, new fuel filter. I saw the old fuel filter and it looked like small pieces of rust or dirt.

I WAS DRIVING OFF FROM A STOP LIGHT AND GOT UP TO 40MPH AND THE CAR JUST DIED AND WOPULDNT START AGAIN, AND I GOT NOT COMPRESSION IN CYLENDER #1

Is it possible to disable the whole PS system and just live with manual steering?
