    Default 2001 Yukon Below Freezing No Start Problem

    Anyone out there experience a no start problem in temps below 25 degrees? I have had the truck towed to the dealer, who returned it to me after 3 days and were unable to solve the problem.(Daily temps hovered below 20 degrees each day during the time they had it). No codes present---there is fuel but no spark in sub freezing temps. Other mechanic friends cannot trace it, but we at one time found a 1626 code when it would not start, which is "theft deterent fuel shutoff"...when it warmed up it started and the code disappeared...Help. Truck is driving me crazy, I do not want to replace it (I love it) but that may be the only solution.

    Did you notify the dealer of that code, when it was brought in, or did you get the code after they returned it to you?

    I told them about the code, but they said they could not find it...everyone is stumped...any thought where we can start to look?
