A much better thought is that the temperature sending unit is at fault and not telling the computer to go into cold start mode to put more fuel into the engine for cold start. Kin of like a choke on a carbureted engine. Have the temperature sending unit replaced and you can get started no problem.

Maybe you have water in the gasoline. You can get a fuel additive to help remove it called Heet.Will it crank but not start or does it do nothing when cold?

Make sure your battery is fully charged and all terminals and connections are clean, first. If the car still makes a clicking sound near the starter its your starter selonoid. Some vehicle models allow you to just replace the selonoid and others require a whole new starter. Either way you'll probably have to remove the whole starter to accomplish the repair.

SOURCE: 06 pontiac grand prix wont start no clicking when you turn the key over even jump starting the battery, has dash lights & radio & parking lights. battery tested good. put a used starter & altinator on

Used parts such as starters and altinators don't last. It might **** but it sounds like you need to buy a new starter,altinator, and battery. Or just start with buying one at a time.

I had the same problem Its your security system failing it is really common in GM vehicles i guess. I took my car in and they wanted a ridiculous amount of money to fix it so i did some research and found a module that you can install yourself and it will bypassed it and i havent had a problem since the car starts every time and i did mine 5 years ago. they have great customer service and if for some reason it doesnt work they will refund you 100% of your money. I checked the list and your car in on there year make and model for the problem.. Hope this helps ya out

You need a new starter solenoid. It is essentially a heavy duty remote switch that is activated by your ignition key switch. The solenoids get stuck or don't conduct well after 6 to10 years.
