1992 Cadilla Seville will not restart after it has run for about an hour. Must leave for several hours before it will restart

  • Anonymous Jan 24, 2010

    Let me add more. When you turn ignition, the seloniod and starter do not engage. This happens after the the car has been driven for about an hour and turned off. If you try to restart the starter doesn't engage.

    We'll try and let you know what happens

Sounds like a temparature sensor problem - mixture is too rich to start hot. try starting it with full throttle - if it will start after 15 seconds of full throttle and cranking the temp sensor is definitely at fault - you wont flood the engine doing this only give more air to the engine.

    is the battery hot when this happens?
    you could have either a damaged battery or overcharging alternator if the battery gets hot or is swollen...


    Possibly the temp sensor is giving a very high reading and thinking it is overheating thus disabling the ignition till it cools down.
    Do what is nessesary to make the engine refuse to start
    then Try disconnecting both temp sensors wires and then starting the car,
    there are 2 sensors, one bolted into the head and one near the thermostat. - they have one wire with a female connector attasched to them, the sensor has a male spade connector. if it starts without the sensors connected try one sensor at a time to find out which one the engine wont run with (the faulty one)
    if it still wont start with both sensors disconnecteds then you will have to run diagnostics at a garage.

I have a 92 sedan deville, the problem i am having is very low heat.The heat is warmer at idle but cooler when driving. I have replaced the water pump, thermostat and flushed engine out.

remove the heater hoses from the connection on the bulkhead and flush the heater rad out ,if it still doesnt work then block the bottom outlet off with a cork and then using a funnel and piece of hose connected to top outlet use a 20% caustic soda solution to fill it with and leave half hour then flush it out again.fancy wasting money on pumps and whatever else ,why didnt you ask me first

1995 Cadillac Seville SLS stalls out

It sounds like it may be time for a new fuel filter, try replacing the fuel filter first. The filter has a life of 30,000 miles or one year, if it has not been changed, good chance that it's the fuel filter. Take not that a dirty fuel filter will make your fuel pump run hotter and will shorten the life of the fuel pump which is the more costly repair of the two. Good luck and keep me posted, Be glad to help you get your car running 100% again.
