Bring a fire truck from another location into Angel Pine, then click Right Analog-stick to start the mission. This should be easier than doing it in Los Santos, San Fierro, the desert, or Las Venturas. When you do it at this location, and you are stuck on a cliff that you cannot get up (for example, if the burning car is on the freeway), take your time by taking the long way. You should only use this method if you have at least three minutes or more time remaining. All fires will not always appear in Angel Pine, as they may also happen in Whetstone or other nearby places. Although this sounds difficult, there are not that many roads near the Angel Pine area which actually makes it easier to complete. If the fire truck gets severely damaged, enable the "Health" code.
