No such thing on your car.
The temp sensor tells the computer what the engine coolant temp is.
If it were faulty you would get a check engine light.
I would have the fuel pressure checked before and after you crank the engine. The pump relay provides power to the pump when you turn the key on to recover some of the lost fuel pressure after the car sits. The one way valve in the pump is supposed to prevent the pressure from dropping.
If the fuel pressure drops to zero it could take some time to crank the engine enough to get it back up.

SOURCE: 2002 ford taurus won't start at first crank in the morning

remove the air filter housing from the throttle body, or if its mult-ported injection, remove the large air duct. Do this the night before. The next day, before cranking and having a spray can of carb. cleaner, spray a couple of shots of carb cleaner either into the large air duct, spray towards the engine, or if its single body injection, spray directly on to the throttle body.

Crank engine immediately, preferrably have some one else sitting in the car to start it after you spray.

If the car even tries to start, replace cold start relay.

SOURCE: Long cold cranking before start

You have a very common problem; your fuel pump needs replaced. Inside the outlet of the fuel pump is a "check valve", that holds fuel pressure from draining back to the tank. What you have happening is the fuel has emptied from the lines and the injector rail; the long cranking period is the time that it takes for the fuel to be pumped back to the engine. Replace the fuel pump & your problem will go away.

SOURCE: 1999 Cadillac Catera - 103,000 miles - cranks but no fire

Hello carol...from the symptons you describe more than likely it's the CPS (crankshaft position sensor.)
The CPS is a common problem on Cateras with these symptoms.
The sensor is a magnetic impulse type that sends a signal to the computer, the computer then triggers the fire signal. When the CPS gets weak, dirty or has low voltage the intermitten no starts occur. It will finally result in a no start at all...Please be aware that a lot of caddy dealers will and have overcharged customers for this common problem by ill advise and replaceing uneeded componets.
Good luck...i hope this helps and will fixya up.

Problems with a new car should be under warrenty. Take it back to your dealer as attempting to repair it may void your warrenty and cost you big money.

Car cold, won't idle. Right. Starts then quit

not specific enough, what kind of car? Year? Make and model could be multiple reasons for these symptoms. Could be something simple that needs service such as the Idle Air Control Valve

94 nissan altima won't start and iddle after cleaning IACV valve

An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air. An idle air control motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the idle air control motor to react slowly, either failure can cause the engine to stall at idle. When a trouble code scan is performed it sometimes won't always detect a failed or weak idle air control motor.

Idle won't work in park or in gear.....motor just cuts down low and than quits this has happened before in cold weather.....am I looking at a sensor problem?

You are going to need intake manifold gaskets. They are basically o-rings that when cold allow air to bypass them creating a vacuum leak. In hot weather, or when engine warms up they swell and seal up the leak. Common problem.

My 2003 Saturn Vue won't start if the engine is not cold. In the morning it starts but if I go out and try to drive a few hours later it won't start until I get off work

Without knowing if there are more things happening, noises, clicks, whirr sounds, or even how hard you drive it...

It typically sounds like a bad or clogged fuel filter... Although I've had some cars do this in the past, once they were heated up and had to wait an hour ow two to start again... that generally meant the fuel pump needed to be replaced.

This is called a Vapor Lock... and try as you might, they will not start

So, before you start going through quite a few external sensors, idle air control motors and egr valves and etc, etc at 85 dollars a pop...

Considering changing the FUEL filter and pour a bottle of gas drier in your fuel tank. You could have some condensation in your fuel and it may be as simple as that.

However if this dont help or the problem starts happening again, I would replace the fuel pump.

Good Luck and Happy Motoring

Power surging

Try cleaning the idle speed control airbypass valve, they get sludged up and cause this kind of idle problem.
