Finally got a code from my truck with my no-start when cold problem. P0628. Looking for recommendations. Go with the stock replacement from Geno's or the Fass high pressure with a lifetime warranty. I have put on 62,000 since March 1 ( i will average 70,000 a year) and it won't be getting any less until I change jobs (or die). What kind of luck have you guys been having with the stock replacement? Or should I not even consider it?
