Car wont start when cold?

Cold start problem in car.Basically noticed when car stands overnight in cold weather.The starting problems in winter in cold mornings.
Basically its fuel pump problem on cold start.
One way to verify that this is the problem, in the morning when the engine is cold, turn the key to on, NOT START, just on. Leave it there for 3 seconds then turn it to off and then repeat this process 3 times.
Then try to start the vehicle.
If it starts right up, the problem is the fuel pump.
What is happening, overnight or when the vehicle sits for a period of time to cool down, the fuel is returning to the fuel tank. The fuel pump has a check valve in the pump that keeps the fuel in the fuel lines to the engine for easy starting.
When the check valve goes bad, all the fuel in the fuel lines drains back to the fuel tank. Then you have to crank, or cycle the key in the ignition to resupply the fuel lines to the engine.
The check valve is part of the fuel pump itself and is only available with the complete fuel pump assembly.
This details will help you.

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

The details for fuel filter replacement and its exact location is as follows :----

See the image shown below:---- Its for 6.6L engine fuel filter.
Same for the 6.0L unless you have the filter that is part of the intank fuel pump module.


Here is the steps for the removal and replacement.
  1. Disconnect the negative battery cables.
  2. Drain the fuel from the fuel filter as follows:
    • Install a hose on the water drain on the water-in-fuel sensor.
    • Place the other end of the hose into an approved container.
    • Drain as much fuel as possible from the fuel filter housing.
    • Tighten the water drain on the water-in-fuel sensor.
  3. Remove or disconnect the following:
    • Water-in-fuel sensor harness connector
    • Fuel filter from the fuel filter/heater element housing

To install:
  1. Install or connect the following:
    • Water-in-fuel sensor in the fuel filter
    NOTE Check the fuel filter/heater element housing and the filter for a dislocated filter seal or foreign debris. Contamination on the filter/heater housing may cause leakage at the fuel filter. Coat the seal with clean engine oil.

    • Fuel filter on the fuel filter/heater element housing
    • Water-in-fuel harness connector
    • Negative battery cables
  2. Prime the fuel system:
    • Pump the primer located on top of the fuel filter 30 times or until stiff.
    • Try to start and run the engine. If the engine does not start, repeat the previous step.
    • Allow the engine to run for 5 minutes at idle.
    • Check for fuel leaks and clear all Diagnostic Trouble Codes (DTCs).
