2009 GMC Acadia will not start after refueling. I have checked the gas pressure from the fuel pump. I do not see a drop in pressure after the fuel pump has primed up to fuel injectors. When at idle the pressure is maintained around 40 PSI when RPM are around 2000 the fuel pressure is at 45 to 50. Should I check my fuel injectors no error code are being generated

I might do a search on the purge solenoid valve.

Will do thank you

Be sure to note about possible part number changes and differences.

That is a classic symptom of a bad purge valve.
Easy and cheap fix.

Heres the symotom and repair.

Been down this road. EZ fix. Sits right on top on the intake. Don't be alarmed if the new one seems to be a bit of a sloppy fit, and that's with OEM.
