Question about Land Rover Discovery
This condition is consistant with a vehicle loosing its prime..meaning, the fuel air mix prime that it was left with when you turn the car off. The longer it sits, the more prime lost, therefore, when driven daily, the prime is good enough to get fuel to the cylinder. When it sits longer, you have to wait for fuel to be pumped from the tank and the fuel system pressurized, before it will start. This can be caused by a bad seal or connection, even injector seals. As the prime is lost, the system likely takes on air, this must be pumped thru the system before you have the proper fuel air mix for restart. To troublshoot, you must check the fuel system, starting for the components that are easily accessable, such as lines, injectors, connections etc. this may have to go all the way to the tank and the fuel pump. You mention in your post that the vehicle is not firing...this would mean that you do not have spark to the cylinder, which you do. The 3 elements that are needed for combustion, (starting), would be fire (spark), compression, and the proper fuel air mix...this is obviously a fuel system related issue. Good Luck! I hope you find this to be very helpful!
