Re: 2003 durango won't start after driving for a while
It sounds like it could be your temperature button also know as a thermostat in newer cars this tell the motor if it is OK to start if the button thinks that the motor is going to be in danger of overheating when starting then it will not allow it to run the button is not connected to the temperature gauge in your dash bored this could mean that you may need your cooling system flushed out very easy i do it once a month to my car
while the motor is cold, on the top of the radiator there is a hose disconnect that not using the smallest amount for force not to break the radiator.
have a running hose ready to go with it turned on and the radiator cap off
start the car and leave it run
quickly got the the radiator and place the hose in the top of the radiator
this will flush out any dirt build up around the button and may help the problem
TURN OFF THE CAR THEN TAKE THE HOSE OUT
put the hose back on the radiator and make shaw it is tight with out damaging the radiator
start the car and fill with coolent
take for a short drive close to home to make shaw you have put the hose on properly
go home and let car sit for about 2 hours
check the radiator and fill if needed
WHEN YOU DO THIS MAKE SHAW YOU DON'T HAVE A WARM MOTOR OR YOU MAY RISK CRACKING THE HEAD OF YOUR MOTOR THIS IS VERY EXPENSIVE IT MUST BE COLD ALSO DONT RUN THE CAR WITH NO WATER IN IT BUT ALSO IN SAYING THAT YOU MUST RUN THE CAR BEFORE PUTING THE HOSE IN THE TOP WHERE THE CAP GOES WHEN DRIVING THE CAR FOR THE FIRST TIME DONT LET THE CAR OVER HEAT IF HOSE COMES OFF THATS WHY YOU NEED TO STAY CLOSE TO HOME

Tune up, air and fuel filters. When was the last time? Also Dodge has several software upgrades for Durango's. Both for the ECM and the TCM. You can call a dealer and ask for your truck, have the VIN number handy, they will need it.
Its likely having problems because of how cold it is. A block heater is beneficial during these times. I recommend getting some starter fluid. Have someone spray it into the intake while you try to start the vehicle. This should get your engine back up and running, if not you may have water in your fuel from the cold weather. You can also try disconnecting your fuel supply lines from the cylinders and trying to crank the car. Once an observer sees fuel flowing in steady spurts reconnect the lines and try starting it. Good luck!
