Question about 2005 Pontiac Grand Am

1 Answer

Check engine light is on and runs hot while stopped.

Had the fuel injector replaced couple weeks ago. Day after getting my car back the service engine light came on. Took it back to shop, now their telling me its the cadalitic converter. Auto Zone says it could be the cadalitic converter and a 02 sensor. Would either of these make it run hot?
Also last couple of days I'm having to give it gas to crank.

Cat could have collapsed and exhaust cant get out efficiently but i doubt a cat has failed or oxy sensor for that matter.Why change 1 injector?the vehicle is only 3 years old and should be under warranty it all sounds quite strange and with no other info or specific details i doubt youll get any intelligent answer.Sounds like a lot of people/places have fiddled with your car with no decent outcome?What was the original problem before taking it to auto shops and mechanics and having to replace an injector?

Someone pour sugar in gas tank


did your engine get hot the second time. if it was me i would have an estimate for everything to be perfect and take the person who did it and take them to court. sugar could ruin your engine, and you could do the same if u run it too lean, cause your cyl head temp could get really hot.

First off, I think you bought a raft of stuff you didn't need on that repair job! The sound of it at this time is that probably the fuel pump is about gone.You need to measure the fuel pressure (engine running) at the fuel rail (the test port looks like a tire valve) above the injectors. The pressure should be in the 45 to 55 PSI range. If the pump is toast, it will be much lower. The pump resides in the fuel tank. You probably have the check engine light on. If the code(s) are read out with a scanner, it will likely point to the fuel pump.

Sounds like you have a small bit of dirt or grit in the fuel system when accelerating it is drawn with enough force to cut off the fuel supply then is released when engine at Idle.
1 run liquid fuel line/injector cleaner in 1 tank
2 check fuel lines for debris
3 change fuel filters
4 have fuel tank flushed
here is trouble shooting order less expense to greater.

Flashing check engine light is missfire, fuel pump probably causing multiple tries to start.Having to build fuel preasure,vac leak on one side of intake probably causing rich/lean condition.Also check back preasure to cat ,Sound like you are moving down right track.Mas air flow would probably set lean code bank1 and lean code bank2

Dodge cummins won't start, fuel reaching injector pump but no fuel coming out of injector pump.


You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?
