how loud is your fuel pump
when mine primes it sounds like there's lots of air in the line, or the pump has an issue... not sure if maybe i just haven't noticed it, but it's starting to get cold here now, and not sure... Would like some insight...
You could take it in and have the dealer do a fuel line pressure test to see if the output is strong enough. Not sure how easy of access the pump is to get up close to it, put a hand on it see if it is vibrating, running rough etc. The last thing you want is a bum fuel pump at -35C when you have to get to work?!
