The TPS ( Throttle position sensor ) is on most newer vehicles. They are located near the throttle body or the throttle cable near the cylinder head. Its purpose is to keep the vehicle at idle speed without having you keep your foot on the gas pedal. when a TPS goes bad, normally your check engine light will come on and your vehicle will not idle properly.

Although maybe possible, most likely not probable. Symptoms of a bad tps include rough idling, fuel-rich signs such as fouled spark plugs, black smoke ROM the exhaust, etc. I have never seen a case where the symptoms were ignored to the point where the vehicle would not start.

The throttle position sensor (TPS) on the 1993 General Motors/Oldsmobile Ciera with the 3.3L V6 is located as part of the throttle body assembly. The removal and reinstall of the TPS is simple between disconnecting and cleaning the wiring harness, and removing the two restraining screws on the bad unit. The OEM AC Delco TPS for this application is part #213915.

get a scanner and check the datastream for the TPS sweep voltage or go to a qualified mechanic for a diagnostic
