Hi people i'm new hear and live in Connecticut. I have a 2007 Crossfire and seam to have the same problem ever one is having with the Po410 code.
I have read most of your recommendations but i must wait till it get at least about freezing hear to check things. My 1931 ford is in my garage taking up that spot.
So this much i do know when i start the car the pump starts and does run for a very short time.(is that a good thing?). The 40 amp fuse is good i checked that.
I think next time it gets a little warm out i will look for the blue check valve. Am i on the right trak.?

thanks Jim
p/s nice site u have hear
