Was serviced 2 months ago, but fuel filter wasnt done? Have had no problems until this really cold weather has hit in, I work nights so drie to work 8 hours of cold weather makes it very hard to start cranks over fine, the oil can light? Flashes with ignition on and takes a while to go out? Would this be anything to do with it? As soon as it does start and I drive 15 foot it's fine runs as normal?
