    sounds like either the automatic choke is not engaging (if it has one) or the air mixture valve it becoming stuck if left over night, google for a diagram of your engine then find this part, remove it (usually 2 small nuts) then as you pul it out you will see a small pin with a spring, spray WD40 on it and push it in and out a few times, replace it then hopefully the problem will be solved.

SOURCE: 2004 mazda rx8 cranks but won't start

Sounds like you flooded it not with water but with fuel due to moving car with out warming it up all the way before shutting it off. You can take it to the dealer and get a flash update to prevent this in the future. To deflood remove spark plugs and let sit with fan on them over night to dry out. Replace and start cranking for 15 seconds at a time till she starts up. GL!

SOURCE: Hello... I got problem with

Your English is very good.

From what you have described, which is a rapid over heating of the radiator coolant fluid and therefore a hot engine condition, it would appear that the thermostat in the engine's cooling system is faulty.

If the thermostat is sticking in the closed or nearly closed position temporarily, there will be no flow or very little coolant flow between the engine and the radiator and the engine will overheat.

You have advised that after the engine is shut off , and radiator coolant fluid has cooled, you re-start the engine and drive the car without the overheating condition occurring again and the radiator coolant temperature is normal. This time there is no overheating because the thermostat is working normally.

You should have the thermostat replaced as soon as possible because allowing the engine to overheat can cause very expensive engine damage.

If you had a continuing overheating condition then I would suspect both the thermostat and the water pump. However as the overheating seems to be only temporary, and clears itself after you have shut down the engine and re-started it 10 minutes later (without further overheating arising) then I think you only have a faulty thermostat.

Please also check that the electric fans which draw air through the radiator are operating. These run on a temperature sensor and will switch on automatically once the radiator coolant fluid reaches a certain temperature and then switch off again when the fluid temperature reduces. You will hear them running once they start up. If these fans are not working the radiator coolant can quickly overheat in various driving and temperature conditions because there will be insufficient air flow through the radiator to cool the fluid. If the temperature sensor is faulty or has died, or if the electric motors running the fans are faulty, the fans will not operate.

I hope this helps.

04 elantra stalls when cold


No codes would point to fuel problem such as low pressure.
Was the car left overnight at the shop so it would be a cold start for the mechanic ?

Car won't start when it gets cold.


Sir,
You are suggested to check you plug wires they might be getting too much carbon on them and another thing is that you can get your car serviced and air filter clean if not done above 2 weeks.

NO START , COLD


have local auto parts store check the battery, it may have a couple bad cells, which would reduce cranking amps... would still have enough to run lights etc., but just not enough juice to start the car...
