Good morning all,
i have a Yale glp060vxeuse serial b875b05472 this unit has become very hard to start recently. our temps have been in the single digits lately and i am wondering if this could be the reason. i saw another post that mentioned that these truck have a pre heater for the lpg system. is this correct?

also could someone tell me how to check fault codes thru the dash. the truck cranks for a long 10-15 seconds but it does start after that. it ran fine during the warmer weather.

any help would be appreciated
