20 Most Recent 1989 Pontiac Sunbird Questions & Answers

Hola, mi recomendacion es antes que nada reemplazar el termostato para iniciar bajo control. el thermostat de mas Baja temp para zonas calidas. Despues de esto asegurar el termostato funciona y abre al llegar a los 90 grados o mitas de ahuja debe de verse circulacion en deposito de agua. En estos vehiculos es importante purgar el sistema por medio de un valvula /tubo loicalizada frente a motor. se afloja y sale aire. cerrar cuando ya no salga aire/vapor. Despues de esto se podran tomar mejores conclusions. Recomendacion nunca quitar termostato permanentemente ya que es necesario en tiempo de invierno/frio para calendar vehuiculo adecuadamente. FIN

you probably have water in the gas.you will have to add "heet"to the gas and maybe even remove the air intake tube and try to start it using starting fluid.

You might have to remove the exhaust. You will need a very small cresent wrench. Have you already tried to get it off?

If the water is dripping out of the water pump, then the water pump needs replaced, if the hoses are leaking then the hoses need replaced and so on for the radiator, if it is leaking then It needs to be looked at by a radiator shop. If the water is just dissapearing and you don't see any leaks and don't have wet spots on the ground, I would have a mechanic check for bad head gasket or a leak in the intake plennum. Do you notice any white smoke from the engine exhaust? Water can leak into the combnustion chamber thru a bad gasket and it will get burned in the cylinder and you can see some white smoke at the exhaust when this happens. You didn't give me much to go on here! But I hope I helped.

There is the possibility that the ignition coil is faulty and first check to see if full battery voltage is getting to the "Pos" (+) positive side of the ignition coil when the key is in the "Run" position, and also that full battery voltage is getting through the "Pos" (+) or positive side of the ignition coil and over to the distributor ignition module, dis-connect the wire connector from the ignition module and if battery voltage is not present at the connector to the ignition module with the key in the "Run" position but it is present at the "Pos" side of the ignition coil, then the ignition coil is faulty. If battery voltage is present then check the ohms between the high tension terminal (where the coil wire goes on the ignition coil) and the "Pos" terminal on the ignition coil by first dis-connecting the wires from the ignition coil and then test with the "Neg" lead from the ohm meter in the high tension terminal on the ignition coil, and the "Pos" lead from the ohm meter to the the "Pos" terminal on the ignition coil, and the ohm reading should be between 6,000 and 30,000 ohms and if not replace the ignition coil. A faulty ignition coil can also damage the ignition module.

The ignition module and the pick-up coil/stator located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil. A faulty ignition module can cause any one of these systems to malfunction.

That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores. If the ignition module does test out alright then the problem could still be in the pick-up coil/stator, (it can be tested using an ohm meter by dis-connecting the wire connector from the pick-up coil/stator and the ohm reading between the two wires from the pick-up coil/stator should be between 500 and 1500 ohm's, and both of the wires from the pick-up coil/stator should show an open loop or an infinite reading between each wire and ground) and if the pick-up coil/stator is found to be faulty then replace the entire distributor, or the distributor will have to be dis-assembled to install a new pick-up coil/stator.

If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.

To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

You could have a bad pump motor in your fuel pump. You will hear the "hum" of the pump motor but it won't continuously feed enough pressue to the system.
When you prime it the engine will draw enough to run for a bit then quit. They usually dry out if not kept full and sunfire fuel pumps are noted for this type of failure.
Try a used one for about 75 bucks. My kids Sunfire did exactly the same thing.

If adding transmission fluid doesn't fix it, you need a new tranny. C'mon, it's a 20 year old car.
