2000 Pontiac Bonneville SSEi starts and immediately dies; will not run without foot constantly on gas pedal

Well pumping the pedal on a fuel injected car does nothing. If there are no trouble codes stored in the computer, look for excessive fuel from the injectors or the fuel pressure regulator. Or lack of air thru the idle air control valve.

Throttle position sensor and or the fuel pump are bad. Throttle position sensor is pretty cheap and easy to replace. Fuel pump is a pain and a little more expensive.

How do I replace my throttle position sensor on a 2003 bonneville ssei

Hi, The tps is located on the side of the throttle body. Disconnect the wiring connector and then the two mounting screws. You may need to wiggle the tps a little to free it from the throttle body. Installing is just the reverse and there is no adjustment for these. Good Luck

The oil pressure sending unit is located behind the oil filter, Threaded into an aluminunm housing. It has wiring that plugs into the sending unit. The oil filter has to be removed and you will need a deep well socket and a 6 inch extension. Change the oil and the sending unit together.
