SOURCE: 2000 gmc rough idle
Im not sure if this can help, but my 2000 gmc sierra was idling badly. Replaced Fuel Pressure Regulator and my truck runs like its brand new. My service engine light was also on.

do you have any check engine lights on? If you do, that is the first thing I would have checked. It does sound like plugged EGR, vacuum leak, or bad TPS

Turn the key on and go have a coffee.If the fuel pump is running it does not mean that is pumping enough fuel to start,the motor may be good but the pump wore out.Try a shot of fuel in the throttle body to see if it starts quicker,if so then you either need a pump or a filter.[you already tried a filter so i'm leading to pump or restricted fuel lines].
