Security/Cold? This is the 2nd time now this has happened....on a very cold MN morning, my car starts - runs just fine. When I want to start it again, the security system acts like I stole the car, and shuts down when I start it. The computer needed to be reset by a mechanic last time, I'm just wondering if it could be easy enough for me to reset? Also - I do not have a keyless fab - I lock and unlock it with my 1 key.

Clean throttle body and change fuel filter.

Would recommend take it back to where you got it serviced last and let them know what happened

Sounds like the cold start solenoid. It is designed to keep the engine running at a set RPM until it reaches a specific engine temp.

Ok, time for car school. The vehicle is operated by the computer, every electrical concept that is. When the engine is cold, it starts fine because the computer has placed it in "cold start mode", putting more fuel into the engine than normally would until Once the engine is warmed up, a temperature sending unit or temp sensor tells the computer to change to normal run mode. IF said temp sensor is faulty and is not telling the computer to make said change, it stays in cold start mode, still dumping excess fuel in the engine that is now not required, cause it's warmed up. Like keeping the choke closed on older vehicles. Now I think you can answer your own question, when this no start action is happening after warm up and it always starts fine when cold, what's the first thing you check ? Right, the unsuspected temp sensor. Change that and no more start problem. Have a wonderful day. Glad I could be of service.

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.

If this happens only when the engine is cold or cool, I would suspect a coolant temperature senor that has lost its calibration.
One way to check would be to have the engine controller scanned when the engine is cool then cold.
The coolant temperature should be the same as the intake air temperature. If the readings are not close to one another, change the coolant sensor.
The coolant temp sensor controls the fuel mixture when the engine is cold, normal or hot.
Good luck, let me know.

Still under warranty?... check that.

Hey well aint mn great -40-50 love it hear any ways im a mechanic and if you can i would tough it out some realy wacky things that i have never seen before have happend in the last few days in the cold its suppose to warm up well im rochester where im from any ways then i would see what it does or get it inside a nice warm shop or grauge for a day and see if it runs ok.

If your battery starts turns the engine over, it is doing it's job well. It sounds like your engine computer is not liking the cold engine. If it has been a while since a tune up, it would not hurt to go ahead and do it, but if it runs ok after it warms up, I sould not worry about it a whole lot. When the engine is cold, the egr valve and other things that are made to limit polution tend to stick and give the computer bad readings. A serious tune up may fix it, and I think should, but you MAY still be in the same boat! That does not FIX it for you, but should ease your mind on the light.

Car sat for 10 days while on vacation.No problems before it was parked. I came back and turned key.....slight click as if battery was dead. Battery is fully charged. Any ideas?
