Sounds like your battery is going bad. If it is running to cool you probably need a new thermostat. this will usually set a code for coolant temp below threshhold

For your battery low charge ,I would suggest you cleaning the terminals and the earth leads.
For not warming up rapidly, you might need to check the thermostat as it might be staying open, thus allowing the coolant to go to the radiator to be cooled down. Check the temperature setting on the thermostat as well when you take it out...you might find another thermostat with a higher setting.
Cheers

Y does my 2001 chevy impala die occasionaly while


Make sure your Car is not on the defective switch list...If not it may be your fuel pump starting to fail..in most cases a bad pump the car should not start right away after shutting down but will start after setting for a short period..until eventually stops all together..you may want to have a pump pressure test done it will detirmne if proper pressure is getting to the injectors or carb...good luck..

Toyota lucida hard to start most times. occasionaly ok. 2.2 diesel. everything seems to work as should


in cold weather diesel gels up and sometimes causes a no start issue..a cetane fuel additive helps with this issue. if temps go below 20 degrees, add a quart per tankful of cetane to the fuel to help start on cold mornings. also diesels require more amperage to crank than gas engines do..thus a stronger battery is needed..

It is possible you are having an issue with the security passlock system. A very common problem with this vehicle. I reseached recalls because of having a similar problem. One minute it's fine, one minutes it's not. Very annoying. Visit www.carcomplaints.com . Type in your vehicle info. When the page of complaints comes up...take a look under electrical issues. Unfortunately, it has affected several years, no one has an answer or fix for it...including Chevrolet & it has not been an official recall. Hope this information is helpful...as far as knowing you're not alone.

Hi...my 2003 impala has a problem with not starting sometimes....just out of the blue it won't start......times vary before i get it to start again, from 10 minutes to 1 hour...the car isn't running...


If you are turning the key and it isn't turning over or anything and all the other electrical is working, there could be a problem with the ignition switch. But also if the theft system has been messed with, it's hard to tell what was messed up and mis-wired.
