For awhile now, my car has had trouble with cold starting. Of course, it never occurs when I bring it to my trusted expert 
He does think it could be a sensor that is under the hood which could need replacing because otherwise the starter, belts, alternator, all that is fine. However, Iâve had no luck finding any information about this sensor.
Of course, it doesnât help that my knowledge of cars extends to knowing where the oil and steering wheel fluid goes
Any thoughts?
any more info? 2 stroke engine? rotary engine? diesel engine?

There are a couple of sensors I think need to be checked. The coolant temperature sensor (CTS), and the ambient air temp sensor. Problems with either will send the wrong data to the computer about cold start needs.
Silly question, but has it been tuned up recently? Are there any computer codes available? Is your check engine light on? Do you smell gasoline when it wonât start? What sensor does your âtrusted expertâ think is failing? The more info you can give, the better the chance someone can help.
Thanks all. I appreciate being asked for details. Iâm never sure what info to convey when it comes to cars.
No check engine light. Six-cylinder 3.5L engine. I donât have the device that can read the computer codes. No gasoline smell when starting, and I havenât had a chance to follow up with my mechanic (keep meaning too but keep getting sent on business tripsâŠ)
Iâll check out the Coolant Temperature Sensor and the Ambient Air Temp.
If the check engine light hasnât come on, there at least arenât any âcriticalâ codes stored. On Chrysler vehicles, you can get a quick listing of codes by turning the ignition on-off-on-off-on. (donât try to start the car, just turn it to âonâ) The codes will blink out on the check engine light. Example, a 55 will be 5 blinks, a short pause, and 5 more blinks. 55 is the last code you will get I believe, and it indicates the display of codes is done, so if you only get a 55, it means no codes are set. Check it and post back. You didnât mention if it had been tuned up recently as Iâd asked.
Ok, Iâll try the code thing. Still need to look at the two sensors from above. Got smacked with a nasty sinus infection so sorta let the car lie for a few days.
If the one, or two, temperature sensors are indicating erroneously to the engine computer, it wonât know, and wonât turn on the check engine light. The resistance (ohms) of the sensors can be measured to indicate if they are accurate.
