replace the coil. Check the operation of the distributor and condenser in the distributor. that is if you don't have an electronic distributor.. Replace the module in the distributor if you have.

Sounds like you have more than one problem.
The seat belt light is not on because of the door.
Are you saying the serpentine belt comes off the engine pulleys ?
And have you checked the battery and starter for voltage ? You need 12 volts at the battery and at the starter, and on the small wire from the starter to the key switch.

If you suspect its a fuel problem best to do a fuel pressure test, you can rent a tester at auto zone and do it yourself. They also can show you how to use it and what pressure it should be. Also if you turn the key to on position you should hear a hum from the gas tank and then a click that is the pump running and the click is the relay, if you don't then the pump isent running, also chk. the fuse and relay, it could be as simple as a blowen fuse or a bad relay.

Should try and replace the Spark Plugs to see if that's the problem

The best way is to remove the door lock relay. this relay may be in one of these locations,
The first is the right side kick panel, the next place to look is the right side of the dash behind side cover, if no side cover then look under right side of dash.

The last place is the glove box.

I have enclosed a wiring diagram also to help you .
You will see the door lock module is also located in the same place as the relay. you can unplug module also.

IN wiring diagram you will see there is also three fuses that control parts of the door lock module, you can also remove them one at a time as you may sure that no other component is getting disabled.

I think the module or relay is the best bet. Good day.3_4_2012_1_18_41_am.gif

The bearings in those old gm products were famous for that. The only way to fix it is to change the bearings, which can be quite a job. It's easier to change the whole steering column if you can find a good used one that has a key.

Probably timing. Aim a timing light at your crankshaft, and see if the mark is jumping back and forth irradically. It should be staying in one spot. If it's jumping around, your timing chain has jumped a cog.
If not the timing, then it's probably bad wires or improper firing order .

This should be what you need.

Not much to work with here. Can you be more specific? Does it stall at random or at certain times? Stopping? Taking off? Is the car fuel injected or carbuerated?

1989 Oldsmobile... | Answered on Sep 14, 2011

Check the bolts that hold the pump and bracket for the pump on the engine. this is a start..

1989 Oldsmobile... | Answered on Sep 03, 2011

Check that the thermostat is opening. otherwise a dirty radiator, inside or out or faulty waterpump or the fan is not going.
Engine timing can sometimes make it overheat.

Most likely your climate control module is bad. Very common on GM. Hope this helps. TJ
