Other Category problem
2003 Chevy Impala 6 cyl Front Wheel Drive Automatic 114000 miles

I HAVE A 03 IMPALA WITH THE 3.4L V-6.. HAD FULL TUNE UP DONE. PLUGS, WIRES,ALL FILTERS, OIL, BATTERY.. BUT I HAVE BEEN HAVING PROBLEMS STARTING IT SOME TIMES.. I HAVE TO CRANK IT AND GIVE IT GAS OR IT WONT START. BUT LAST NIGHT I GOT IT STARTED BY APPLYING GAS PEDAL BUT EVEN AFTER IT WAS ON, IT WOULD DIE OUT AS SOON AS I LET OFF GAS PEDAL.. SO NOW I CANT DRIVE IT BECAUSE IT WILL DIE AS SOON AS I LET OFF THE ACCELERATOR.. I THINK IT IS PROBABLY MY FUEL PUMP.. BUT I DONT KNOW FOR SURE.. I NEED HELP ON THIS ONE

First, have it scanned for trouble codes. Then post any codes for us. You could try cleaning the throttle body out.

OK I REPLACED MY FUEL FILTER.. TURNED OUT TO BE CLOGGED UP REALLY BAD.. BUT MY 03 IMPALA STILL HAS PROBLEMS STAYING ON.. IT DOES WORK SOMETIMES AND THEN SOMETIMES IT JUST WONT START AT ALL.. I HAD IT SCANNED AND MY EGR SENSOR CAME BACK AS A CODE.. COULD THE EGR MAKE MY CAR NOT STAY ON OR MAKE IT NOT TURN ON??

Yes, a stuck open EGR valve can cause the engine to die at idle. Please post the code number for me. You should also check the fuel pressure. I think it should be around 52-56 psi.
