Question about 1989 Buick Century

1 Answer

Ok when i am drivin my car the check engine light and the temperature light comes on, it doesnt have a guage so i cannot tell if it is just coming on because of a short or what, it only does it when it wants to do it, so i can drive for 3 days straight and then on the 4th day it will deside to do it. Also the fan won't come on all the time, It also idle's super super high sounds like a darn jet plane but it only does that when the lights come on, when they do the car can drive sometimes but it acts like the fuel pump is bad in it and it bogs really bad and dies 9/10 times, the auto mechanic i took it to said it was a bad coil pack??? I replaced the coil pack with a chrysler one, not really sure if it matters cause they look 99% the same, but after doin this it didn't effect the problem in the car, also the exhaust pipe leading from the front of the motor was red cherry hot one time but has never done it before or after that drive.... I really need to no what is wrong...

One thing that may be causing problems for you, and it would probably be the first thing I would check is your catalytic converter for being plugged. Engine bogs, and manifold red hot, temperature light, would be reason enough for me to get that checked. Years ago, you could buy what they referred to as a test pipe, for that, which was basically a piece of exhaust pipe put in place of converter, which I suspect any custom exhaust place with bender, can fabricate for you, if necessary. Check oil & coolant levels too, as oil may be experiencing premature thinning due to excessive heat, as well as coolant level going down. Hopefully if it is confirmed converter is problem, we caught it soon enough .

My temperature gauge don't move and my check engine light does not come on


Bulb is possibly out behind the instrument cluster for the check engine light. As far as the temperature guage not working it sounds like your temperature sending unit is not working if it doesn't move at all. If your thermostat is stuck open it would come up some. If not your temperature sending unit is bad.

You NEED to go back to that shop and tell them to make it right-or call the state attorney generals office if they wont. They should never have told you to leave with a idiot light on after doing the work on your car!

Check engine light comes on and then the temperature gauge goes up to hot


Mine did it too.... The problem is the Engine Power Relay.

The Engine Power Relay is in the relay box in the engine compartment. Aftermarket relay is cheap, but the original Ssangyong part will last many years longer.

Hope this helps.

Service engine soon light comes on and gas guage does not work


IT SOUNDS LIKE YOU HAVE 2 UNRELATED PROBLEMS. THE CHECK ENGINE LIGHT 9 OT OF 10 TIMES IS DUE TO AN O2 SENSOR, ITS PART OF YOUR SMOG EQUIPMENT. IF YOU DRIVE RELATIVELY SHORT DISTANCES ALL THE TIME THE OXYGEN SENSORS WILL GET PLUGGED CAUSING THE LIGHT TO COME ON, REPLACING THE OXYGEN SENSORS ISNT A BIG DEAL. NOW FOR THE GAS GUAGE NOT WORKING, IT COULD BE A FEW THINGS, FIRST CHECK YOUR FUSES, IF THEY ARE OK, IT COULD BE A RELAY, A BAD GUAGE OR JUST A LOOSE WIRE TO THE GUAGE,OR THE SENDING UNIT FROM THE TANK TO THE GUAGE. BUT MOST LIKELY ITS PROBABLY A SENSOR THAT HAS GONE BAD.

The oil light comes on at times and goes off as the rpms go up. What can be done about the light?


Maybe your engine is idling too slowly, If the revs are below say 700rpm the low pressure warning light could come on especially when the engine is hot.. If the idle speed is ok try a heavier grade of oil in the engine. Next try a new oil pressure sensor. It's got to be one of these things. Check the engine running temperature . An over-hot engine will cause the oil light to come on too.

1989 buick century problems


I can only help with a couple of the problems....you probably need new fan relay switches which if you are facing the car usually mounted on the front left hand side.....if they are bad the fan will not run, if the fan is not running your car will overheat. The fan relay switches look like black square boxes, I believe there are two of them, high speed and low speed.
