Hi
It is RAM 92 5.9turbo.
When is cold like now close to frost, I need crank ~30second to start. When they start , next start need just one crank.I did check air heater system - is not working(heating elements are OK).It is like computer is not giving signal to relays.Do we have some temp sensor sending message to comp to start air heating system? What fore is this KSB sensor on the intake maifold?Do we have any cut-off fuel valve(sorry for my poor english)
