2003 MODEL.has any one come across bad starting from hot or cold, it will start but you must , crank for over a minute, yes is the fuel runing back, change fuel filter and check connections, looks like fuel in plastic line, no bubbles , i think poss weak fuel pump, because if you jump it and the engin spins fast it will start ok, untill you leave it for 4+ hrs, some times its a pig only after 5 mins?

the other pain is the viscoss fan sounds like it a plain, so replace it still the same, then it was ok for a hr, are there flaps or switch that open and close air vents on or off ??
