Still a brand new truck, why does it start like my 2000 when the fuel pressure regulator went bad? Every morning and every evening it cranks 2-3 times normal before it starts. This is supposedly because the fuel injectors inject fuel directly into the cylinder which requires more pressure, but then why does it start fine if it has been run within the past couple of hours? Where does the pressure go? Why can't you change it so the fuel pump comes on before the starter engages? There must be a better solution than to simply call this normal.
Is this seriously the best GM can do?

Just in the last three weeks, I've noticed a hard start issue, plus a rough idling issue. I thought it might be the fuel I was running, so i used premium fuel several times with a fuel injection cleaner, but no help. I see that this has been reported with no cures yet, but at times it's really rough idling & poor take off from a stop. You can actually see the tach needle bouncing up & down at idle. It also hesitates some on take off & while turning, like its not taking the fuel as you press on the gas pedal...
taking the truck back in for many issues next week to get checked again & add this one & a few more too!
I wished I had my 2011 GMC trk back now!
