#1

Hi, I’m wondering where the mass airflow sensor is located on a 2004 Pontiac Bonneville?

It’s mounted on top of the throttle body.

thank you, do you know how to tell if it’s working properly? my car isn’t starting and I’m running out of problems it could be

Has the Check Engine light been on before the no-start condition?

yeah

Then that’s where you have to start.

You need to have someone hook a scanner up to the vehicle to determine if there are any codes that may be related as to why the engine won’t start.

Other than that, it’s anyone’s guess.

If your car isn’t starting and you suspect a bad MAF, unplug it. That will tell if the MAF is stopping it from starting. I would bet by the vintage, it’s a bad fuel pump.
