06 cxl with 3.6l. Car is very difficult to start only at the first start after a fill-up.

Asked by lupie989 Feb 04, 2011 at 08:31 PM about the 2006 Buick Rendezvous CXL AWD

Question type: Maintenance & Repair

It either acts like it is flooded or starved for fuel.  It will start after repeated long cranks, produces low RPM but eventually clears to normal.  It has never done this outside of a gas station visit. It does not throw a code.  Any suggestions?
