Script not identifying Value change?

Added a fuel and damage system to an AC6 Chassis. The Damage system calculates the damage correctly but fails to activate the 2nd part of the script which kills the vehicle.

The strange part, when you jump out the vehicle and enter it, the script registers the damage.

The Script is a Local Script.

wait(.1)
local car = script.Parent.Car.Value
local dmghandler = car.Body.dmghandler
local per = script.Parent.AC6T_Stock_Gauges.dmg.Text
wait(.1)

function crashed(crash)
	wait(.1)
	if dmghandler.Velocity.Magnitude > crash.Velocity.Magnitude + 5 and crash.CanCollide == true or crash.Velocity.Magnitude > dmghandler.Velocity.Magnitude + 5 then
		script.Disabled = true
		dmghandler.dmg.Value = dmghandler.dmg.Value - dmghandler.Velocity.Magnitude / 0.4
		script.Disabled = false
		
	elseif 0 >= dmghandler.dmg.Value then
		print("Car Dead")
					script.Disabled = true
					dmghandler.dmg.Value = 0
					script.Parent.Values.Torque.Value = 0
					script.Parent.Values.Gear.Value = 0
					script.Parent.IsOn.Value = false
					script.Parent.Dead.Value = true
					
			end
		end
	
dmghandler.Touched:connect(crashed)

Any help is appreciated.

Thanks, Bradolink
