I find it hard to start my l 200 after running several minutes.i could start it in the morning after I on the switch what ,s the problem.


May just be a bad temperature sending unit. Once warmed up, it's supposed to go off cold start, which puts more fuel to the engine. If sending unit is not telling the computer the engine is warm, it will still be putting more fuel into the engine and flooding it, making it hard to start. Check/replace said sending unit and you're good.

Does the 2002 regal have a cold motor sensor Car hard to start when cold motor (in the morning )


Your vehicle uses the coolant temp sensor and the intake air temp sensor to determine the engines temperature on a cold start. If one of them is dramatically different than the other it will flag a code.

Is the check engine light on?

When was the last time you had a tune-up? if recently what brand of plugs where used?

Have you noticed any hard start issues after a hot soak? A hot soak would be driving the car until fully warmed up, shutting of the engine for approximately 15 to 20 minutes, and then starting the engine again.

The way to test a fuel pump is to put a pressure gauge on it in the morning when it is cold when you have the problem. If the pressure is low then your fuel pump isn't working when it is energized.

If it is high, but it is still hard to start, look at a fuel injector being plugged up.

Car starts poorly during cold mornings. The idle


Sounds like a cold start valve (which is actually an additional injector in the intake to assist in cold starting) If you can get it to your local prts store while the light is on they will read the codes for free and tell you what the car thinks is amiss.

Re: 2003 audi a6 not cranking when cold


try running lighter weight oil in the winter time, if the oil is too cold the starter will have to work extra hard to turn the engine over and sometimes this will cause fuel problems because the injectors are timed with the engine.

Hard to start when the engine is hot


Sounds like electronic ignition problems, I had a truck and it started doing that and then it would not start at all hot. You would have to wait for it to cool completely, then it would start right up. Ignition module problem is what it sounds like.

Hard to start on cold mornings but starts fine when warm


The cold start valve is not operating correctly. Either the engine coolant temperature sensor is bad or the cold start valve itself is bad. You can check the engine coolant temperature sensor by going to radio shack or any electronic store and purchase a 15k ohm or higher resistor. Disconnect the engine coolant temperature sensor (ECTS) harness. Bridge the 2 female spade connections in the harness with the resistor. Start the engine. If the engine starts you need to replace the ECTS. If the engine is still hard to start, you need to remove the cold start valve, (wear safety goggles, and whatever you do don't smoke) place the cold start valve in a glass and have someone crank the engine. You should see gas coming out from the cold start valve. If not take a ohm meter and measure the terminal at the cold start valve after disconnecting the wire harness. The meter should read 25 ohms. If it doesn't replace the cold start valve.
