Hey guys
My 2009 had engine lights flash off and on this moring. then power was sucked dry and seemed like it was bogging out, exauslt sputtered. The car drove like that for a bit then shutt off. Now it will start up but shut off again. Any Ideas? It was -17 this moring here in Nova Scotia

YUP, Good One grullon10

especially if with ethanol fuel even at 10%.
It is hygroscopic and even a small amount of moisture would freeze and cause a restriction in fuel flow.

New Brunswick, Newfoundland, Nova Scotia, PEI: all premium grade gasoline are ethanol-free.

There is a fuel pressure test port at the fuel rail Should be around 384–425 kPa (55–61 psi)
