Sentra Starts like 71 Buick when "cold"

I have a 1997 Nissan Sentra GXE. It starts properly when the engine is “warm”…however, if the car has been sitting for a few hours or more, then I have to turn the key several separate times before it will fire and/or start. Sometimes I even have to pump the gas pedal like I used to do with my old carberated vehicles 30 years ago to get it running. This happens summer or winter. Seems fuel starved when “cold” for some reason. Ever heard of this?

Yes, it may be fuel starved. A dirty fuel filter will do that. You need to check fuel pressure.
