I got a remote start put in my expedition and it wont remote start in cold weather like under 15 degrees after sitting for more than like 5 hours it will start like in 20 or 30 but not like under 15 it wants to start with remote start it just keeps cranking over it feels like it wants too but doesnt so i have to go out and start it by hand by turning ignition and giving it gas thats the only way it starts i replaced the fuel filter thinkin that was it but it wasnt any other suggestions please
