Lift would give trouble starting when cold in the mornings but once it got running and got up to temp it would start and run no problems. Today was much colder than any other morning in a while and the lift would simply not start. I have spark ,compression.. the LPG fuel pressure regulator is 6 months old... what would casue a lift to not want to start when cold?? Im pretty sure if it warms up tommorow it will start right up.. problem is its bound to get cold and stay that way for a while and my problems will return. Any help is greatly appreciated.

Thanks,
Ray.
