Starts....Stalls....Starts and runs.
Hello all,
I have an '05 Monte with the 3.8 L V6. It will fire and then immediately die. I replaced the air cleaner and that helped, but still some issues. It coded with "Bank 1 too rich". I replaced the MAF about a year ago. I am assuming injector issues, maybe fuel pump? It has 130K miles.
Any ideas would help.
Thank you

sounds like maybe the fuel presuure regulator
What causes the P0172 code?
What causes the P0172 code?
- A dirty mass air flow sensor overstating the amount of air entering the engine which may cause excessive fuel delivery
- A bad oxygen sensor
- A leaking fuel injector allowing too much fuel to enter the combustion chamber
- A faulty fuel regulator, which may not be regulating the pressure of the going to the engine as it should
- A vacuum leak
- A possible fault in the coolant system such as a stuck thermostat or bad coolant temperature sensor
- Worn spark plugs
