Sounds like you have a short in the wiring some place that is providing power to the ignition and computer with the key switch off.
You may have to test the circuits with a test light to find the short.
Could also be a faulty relay.

1994 Caprice LS. Little to NO heat.


It will be the heater core. If you can smell it inside the car and it's steaming up the windows the core will need to be replaced. Remove the heater core housing and check to make sure its leaking from the core itself. You might get lucky and have a leak from the hoses running to core instead. Hope that helped.

I have a 94 caprice classic that wil crank but it wont turn on. It just got a new ignition and key for it and it still is doing this problem. it says press key fault and low oil pressure then it shuts off....


You vehicle is equipt with a fail safe switch incase your oil pressure is low it shuts off the fuel pump, More likely your oil pressure switch will need to be replaced,its 2011 relace the oil pressure switch more likely the sensor itself has failed,(oil breaks plastic after awhile,) make sure you have motor oil in the crankcase check the level,

1994 chevy caprice no heat. changed termostat. antifreeze full. fans in back of radiator are not moving


Heater core is plugged or you have a air pocket. If you take off the heater lines and try blowing through them both ways. The fans will not move until the engine gets hot.
