Strong fuel odor at extreme temperatures
1999 Ranger 3.0 automatic, flex fuel option, 130k. I am having a recurring problem when the weather gets close to 0 degrees. The truck starts and runs great but there is a very strong fuel smell in and around the truck within a few seconds of starting it. There is no evidence of a leak and no residual smell after the truck sits for a few minutes. It only happens when the weather is extremely cold and is back to normal at (approx.) +10 degrees or above. Thinking one of the sensors is getting wacky at the low temp and causing the rich mixture. Any ideas?
