My 2000 dodge durango had code p 0206 which I fixed after replacing injectors, spark plugs, tps and finally the pigtail to injector 6. the car now runs great except that when it is cold i have to crank it for ove 5 seconds before it fires. once it runs for a few min it turns over immediately but if it sits for more than 10 min it needs to crank for a few seconds first. any help would be appriceated
Year: 2000Make: Dodge
Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.There is a possibility that the fuel pressure has to build up when you are starting it. You will want to see first that there is fuel pressure when the key is first turned on and that it holds for at least 10 minutes.
Before turning the key there is no pressure at the release valve.When I turn the key but don't try to start it the pressure at the realese valve is minimal pressure (a very small squirt then nothing) after starting it is fully pressurized
It sounds like the fuel pump is coming on, (the relay is working) but the pressure is not up to specs until it has run for a little while. That would normally be in the fuel pump, (allowing the pressure to bleed back into the tank)
NOTE: Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity Test. Check Valve Operation The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine OFF) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1 - 2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by:
