My girlfriend owns a 2000 Honda S2000 and during the cold seasons it cannot be parked outside. If it is, it is very hard to start in the morning or will not start at all. Any ideas or suggestions?

by cold seasons do you mean you live in the northern states? is so yeah that will cause a problem fuel becomes more dense the colder it is therefore making it harder to start some cars have an electric heater installed in them to keep the block from freezing overnight so its a good idea to keep it indoors and possibly clean out the air filter and or throttle body and maybe the fuel filter needs replacing a dirty fuel filter will starve the motor making it very hard to start

Take a look at the owners manual, It has a procedure to start hondas in cold weather, It basicly says to push the gas pedal down halfway while cranking and if you are still having trouble push it to the floor. Check it out.
