Question about 2002 Pontiac Bonneville

2 Answers

Occassionally my 2002 Pontiac Bonneville will not start. (about one out of 10-15 starting attempts) It does not throw a fault code and the fuel pressure is in the normal range. It turns over fine but acts as if it is not getting fuel or the electronics are not letting the fuel ignite. The problem normally happens when the car is shut off and then restarted within 15 minutes. Letting it sit for an hour before restarting has always "cured" the problem. Also, occassionally while driving it will "baulk" momentarily. The fuel filter has been replaced. Any advice on this problem is apprediated.

I know this i s a late response. But I had a bonneville that it turned out to be the control module? I went to a junk yard and got one to replace mine and the it all worked good again.

they are all emission faults

P0453 OBD-II Trouble Code: Evaporative Emission Control Pressure Sensor High Input. P0453 code means that a reading from the engine's evaporative pressure sensor is higher than normal due to fuel tank vapor leaks into the system.

saturated carbon canister
sensor faulty
rubber evap hoses at the tank perished

idea
check the tank fuel cap seal is working
replace the cap is one possible cause

check the fuel pump pressure or for injector rail leak
P0446 Evaporative Emission Control System Vent Control Circuit Malfunction. The code P0446 is set when the engine computer recognizes a fault or restriction at the vent control part of the Evaporative emission control system (EVAP).

The Code P0452 indicates that the Evaporative Pressure Sensor is indicating pressure change values that are below specification, during the EVAP Monitor test and/or the operation of the vehicle.

It will not start and it is acting like it is no getting any gas


When turning the key to the ON position without starting the engine, you should hear the fuel pump running for 5 seconds. If heard the oil pressure switch is doing its job operating the circuit to the pump. If not heard the oil switch is at fault. Upon starting the engine the oil switch has a 3rd wire running to the fuel pump. When the engine fires and oil pressure is achieved, the computer shuts off the oil switch and tuns on the fuel pump relay. If the pump runs with the key on replace the relay. You say it will not start at all so probably the oil sending unit or switch we'll cal it is at fault

Yes you can do it...In repair centre your car will be undergoing a scan with computer which will throw out the fault codes...Once you get the fault codes it will describe which part is faulty what must be replaced, why..

So instead of shooting in the dark it will be like hit the fault and get it rectified..Most autozone shops does the scanning for free...

I have a 2000 Bonneville - I had a problem with the car stalling out - then it did not want to start back up. (When it did it would idle up and down and then die) I changed out the mass air flow sensor - now I have not had a problem. Good luck with it.
