What do i look for when my 2004 pontiac bonneville shuts off?

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.

most people who do not do the first step generally go crazy chasing the problem
the first step is to have the fault codes read as they are there as a diagnostic tool to stop people from going crazy

Fuel Pressure regulator ..maybe

Turn the Key to the 'ON' position, the fuel pump should run for about 1 second. listen for it. Do this a few times without trying to start the car. This should pressurize the system. now try starting the car. There may be air in the system from changing the filter.

Mass airflow sensor ? Is the check engine light lit ? What engine - 3.8 or 4.6 ? TPS - throttle postion sensor

check that the pins in the relay socket and the PCM connector are good and make contact youshouldsee12v at pcm... PCM is last resort. Check the fuel relay first for melting or burnt smell.

replace temp. sensor...hope it helps

crank position sensor...if the engine will start and run for a second or two then it dies. If, however, you can press and hold the gas pedal slightly and keep the engine going, then I would suspect the IAC-idle air control valve. This can be cleaned with spray carb cleaner.

hmm

1.) turn ignition on,, let it sit for 30 seconds
2.) switch ignition off
3.) start..

if it starts then your fuel pump is pushing enogh pressure ,, u will need to get it changed,,

if it doesnt check your oxygen sensor,, and engine coolant temperature,, both of these control the oxygen fuel mixture and chances are one if malfunctioning..

have 1995 pontiac bonniville sse fuel all the way to injectors will run if you put fuel into intake then starts and runs till fuel runs out. I have replaced fuel pump and fuel pump filter,cam postion sensor and coil paks

did you check the timing?
