i have a 2006 pontiac grand prix and when i fill up the gas tank sometimes it wont start. it will turnover it just wont start running unless i push the gas a little. what is wrong with it??
Might be your Fuel pump is starting to fail.
Sounds like your purge valve is stuck open. When this happens gasoline can be forced up into the engine causing it to flood out. By depressing the gas pedal you're leaning out the air/fuel mixture and helping to clear the excess fuel faster. HTH. -Jim
I had same problem
