The engine will not start if you have overheated it.You will need to have someone to find out the cause and have it repaired.Could be faulty electric fan or temperature sensor.Also bad water pump blown head gasket or cracked head or block.

Engine cranks for 8-10 seconds before it starts when engine is warm


you must RUN the SCANNER/computer for better diagnostic and fix it. YOu can have some faulty like: PCM+BCM+ignition coil, sensor, etc. see the diagram attached.

Tip

Heating up your car


It seems simple, but you can make a big difference by turning off your radio, wipers, climate control, all of those accessories, when you start the car. Most of the wear on the engine happens when you start the car, and by turning off those accessories, your engine doesn’t have to work as hard when starting.
Another thing people do is revving the engine in the winter. This actually doesn’t help “warm up” the car. Although it does technically make the engine hotter, it’s not the kind of “warming up” that you want. Revving your engine in the winter causes extreme temperature changes right away, which is actually the opposite of what you want. When you start the car, the oil hasn’t yet worked its way through the system, so the engine is working without lubricant. The right way to do it is just let the car sit and idle for about 30 seconds to a minute at the least.

I have a 3 month old corolla 2012 le automatic. The engine temperature stays below C when I start the car in the morning and heating doesn't work. Even letting the engine run on idle for a few min


You need to have the dealer look at this, if you fool around with it you can void your warranty. Toyota looks for any legal excuse to void the warranty.

I need reset light check engine


You should have the code scanned to see what's triggering the light. Once the issue is fixed after 3-4 heat cycles (long rides) the light should turn off. If it doesn't you may have to have an auto repair shop clear the code for you.

Hope this helps you out.

Starts cold but sputters and dies when hot


It sounds like it is getting too much fuel. check your fuel sensor. Your choke is sticking open. Buy some carb cleaner. Remove your air filter and spray the linkage to clean it up. Make sure it moves easy. Start your car up. the butter fly on top of the carb will be closed all the way. As the motor warms up this should open up gradually. If it doesn't you have a problem with the choke system and it is not letting air in as the motor warms up.

2002 Yukon Hesitation when starting- No checking engine lights!!


This can be fuel pump related or just fuel filter related, spark plugs and injectors.
When engine is cold vaporization of gasoline is minimum. When fuel vapor is less than required and the fuel mixture is not ideal, ignition happens harder than it does under ideal running conditions of engine. When fuel pups is sweak, or filter is limiting, or fuel injectors are not injecting gasoline with improper pattern inside engine, or just becasue of corroded spark plugs, cold engine faces difficulties during first ignition.

PS: sometimes car starts and stalls.it fails to start once more. this can be a sign of broken crank position sensor. FYI.

My 94 Blazer (125,000 miles) has run great since I bought it 5 years ago but recently developed a problem. When I drive it on warm/hot days, it starts right up when cold but after driving even for a short...


Hot starting problems are usually fuel related. When a hot engine is shut off, the temperature of the engine and everything on it continues to rise for awhile as the engine undergoes a period of "heat soak." This can cause fuel to boil inside the carburetor bowl, fuel lines and fuel filter. When you attempt to restart the engine, "vapor lock" obstructs the flow of fuel and the engine doesn't want to start.

This is much less of a problem on fuel injected engines because the fuel is usually under much higher pressure inside the injectors and fuel line. Even so, a fuel line routed near an exhaust manifold or a fuel rail that's exposed to a lot of heat may still suffer the same kind of problems.

Heat soak problems such as these can sometimes be cured by wrapping insulation around affected fuel lines, and/or installing an insulating spacer or heat shield under the carburetor.
A Seasonal Problem

Hard hard starting tends to be a seasonal problem, but may be worse in the early months of spring when refiners are switching fuel blends. Gasoline refiners produce fuel with a slightly lower volatility rating (called "Reed vapor pressure") during hot summer months because lower volatility fuel is less likely to boil and cause hot starting problems. During the winter, they switch to a higher volatility fuel because it makes cold starting easier. But if you still have "winter" grade fuel in your tank when warm spring weather arrives, you may experience some hot starting problems. The problem will go away, however, as soon as the refiners in your area switch to their summer grade fuel.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Check the waterpump and thermostat. When the waterpump doesn't turn, engine heat is not transported to the radiator. When the thermostat doesn't open once warm the same happens - no engine cooling.

The radiator should be hot op top and cooler at the bottom. If it's cold allover then there's no cooling fluid transport

Once i start my car and turn on the heat, it starts blowing in cold air until i get on the road and accelerate more, then the heat starts coming. but once the heat starts it only lasts about two minutes...


Hi Jens,

Two things are happening.

The first is normal. Your heater gets its heat from the coolant ciculating in your engine. In order for it to work, the coolant needs time to heat up a bit. This is true of just about every vehicle.

When it gets cold again is the puzzler.

My advice is to check the coolant level in the radiator.

ONLY when the engine has cooled.

If the level is down, there can be times when there isn't enough water to cool the engine, fill the radiator and the heater core. The result is the heater blows cold air and the engine runs hotter than normal.

So check the coolant. Open the cap. Start the engine and top it off.

Then see if there is a change.

Best regards,
Mike
