Sounds like you may have fuel filter problem. you may want to check the pump and filters located in or near the fuel tank.
Go directly to the source ( Fuel Tank, Pump, Filters, Fuel Pressure Regulator and Injectors )
You may have water or grit in the fuel
Hope this helps

My 2001 GMC Sonoma is idling rough, starts hard but when accelerates sounds good. I have replaced the fuel pump, fuel filter, and now all the plugs and wires, but still rough?


Check for vacumn leaks ! Idle air compensator? clean throttle valve oppenings and air port opening,do you have check engine lite on,check EGR valve? Dirty fuel injectors ,bad pressure regulator?Check fuel pressure at fuel rail,at idle !

I just replaced the battery in my 2000 gmc seirra. The truck cranks right up and will run fine for a minute or two. Then my battery acks like it is going to die, but if I shift it into park everything goes...


Did you make she that the battery has the right cold cranking amps, or the alternator? some times on an alternator the selfegnighter might have gone bad. Also sounds like there might be a wiring or fuel injection problem. Is there a check engine light on? Start simple, put some sea foam in the gas tank (you can get sea foam at auto zone for 10.00) that might cure the rough idle.

Noisy fuel pump


sounds like they need replace the pump again becuse if was good pump it would not do this.
This way amercain cars are not selling good all the jeeps have this dam problem to.
They put bad pump tell them do the job correct dig the paper work out man. Look up for better after market pump and make them do the labor becuse this one is trashed allready. Also leting your tank go below half tank shorts out all pumps faster and after market cleaners mess up the pumps and the gas liner inside i read isent that great
