When i try to start it cold it smell fuel, and when I remove the fuel pump relay it starts for some while then after returning the relay it starts normally.
I need you help to fix the problem.
Note: I have changed the coolant cold start sensor and the situation is still the same.

Maybe the crank position sensor, long starts are usually due to the fact the computer doesn't know where the NO.1 cylinder is, so he fires at random and eventually he nails it, therefore the car starts.
The crank position sensor tells the computer where the NO.1 piston is at and he knows when to send the spark, but u should have a check engine light on in this case.

Dear Megadeth,
Exactly that was the prob. the crank position sensor tell the computer a false information so fuel miss the spark.
The main cause was the defected coolant temp. sensor who was seding false data to the computer, so the computer was generating a wrong orders to the injection system.
The prob has been changed by replacing the coolant temp sensor.
Thanks a lot for ;your kind assitance.
Regards
Imad
