1. Turn the ignition to run (one position before starting engine).
2. Use a paperclip to push and hold the RESET button for 5 seconds. The CHANGE OIL SOON indicator flashes to indicate the system is reset.

1991 BUICK Park Avenue Maintenance Light ... - Oil Reset

Turn the key on, press the gas pedal three times within five seconds slowly. The light will flash, turn it off. reset done.

leave car in run position till light stops flashing takes mine around ten minutes when stops turn key all the way off then should start right up happens to a lot of GM vehicles and mine does it all the time

Have you checked your oil? Low oil will cause that sound.

It is possible that the tumblers in the ignition need lubrication. I had this problem with a boat ignition. Spray a small amount of break free, or WD 40 or graphite penetrating oil into the slot and slowly work the key gently into it. A drop of oil in the slots of the key won't hurt.

The code indicates the TPS is still bad and the code is usually right, but it could be a wiring issue at the TPS connector or less likely a computer issue.
To test the TPS circuit, you need to check voltage and ground from the ECM - 5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector. Checking the TPS signal circuit to the ECM requires monitoring the TPS signal on a scan tool while jumping the 5v reference and the signal circuits. The TPS reading should go from high when the circuit is jumpered to low when the jumper is removed.

Have you tried the reset method? Turn key to the ON position and leave it there for 10 minutes, or until the security light goes off. Then turn key to off, and back to on and start-see if it starts after letting it sit for a few minutes like that with the key in the on position.

i have a 1997 park ave and none of the windows will work i changed relays fuses checked motors changed window switches i need help

You have to reset the check engine oil level light. The light is just a 3 month reminder that lets you know when to change your oil. You have to hold the reset button on your dash for more then 5 to 10 sec. The procedure is in the owners manual that came with the car.

Yes, replace the sensor its close to th oil filter.
