Question about 2002 Pontiac Bonneville

1 Answer

My 2002 Bonneville Pontiac occassionally will not start. It happens when the car has been shut off for a period of 20 minutes or less. The 3.8 liter engine turns over fine but acts as if it is not getting fuel or the electronics are not letting the gas ignite. The fuel filter has been changed, there are no fault codes, and the fuel pressure is in the normal range. Also, occassionally while driving the engine will "balk" and then run fine again. Any help will be greatly appreciated.

Have you changed the crank sensor? When it is shut off the crank sensor acts like a heat sink and when the car is off, the temp of the sensor itself will rise then fall after a while-that might explain your problems, along with the occasional 'balk'-not difficult or overly expensive to replace too.

Why does my 2004 pontiac bonneville start up then shut off after 2-3 minutes?


Remove the O2 sensor on the back side of the engine exhaust manifold. Start it, if it runs for more than the 2 or 3 minutes, replace the catalytic converter. 455 is a purge solenoid code. This wouldn't keep the car from running.

95 Bonneville won't start when hot


Yes I know, but If you hold the accelerator pedal to the floor on a fuel injected car, the Throttle position sensor will tell the computer to enter clear flood mode. Then the computer will shut off the fuel injectors while you have the pedal to the floor. If it is flooded, you should be able to get it started in clear flood.
