Re: 2003 grand Prix: new fuel pump not working
I found a website that says I should be able to take the fuel line off and blow through it, pushing and and hearing bubbles in the tank. As I am sure you know, the person who posted this could be correct or could be a raging lunatic. Csan you tell me if this is true?
Re: 2003 grand Prix: new fuel pump not working
Blowing through the fuel line isn't going to help your low voltage problem any way you look at it, so it doesn't matter if that person is correct or not. It won't make a bit of difference either way.

Re: 2003 grand Prix: new fuel pump not working
have u tried swapping the idle air control? Its a cheap part but it could cause the car to not have enough gas if its putting too much air in the mixture if not that I would shoot for the fuel pressure regulator or maybe a bad throttle position sensor...
