Car (2005 Toyota Corolla) won't start when it is very cold. It will not crank at all. It is NOT the battery! I can have the headlights on and try to start and the headlights don't dim at all. When the weather warms up, it starts. I want to replace the starter, but I physically can't do it and it is expensive to do as a step of troubleshooting if it doesn't fix the problem

STARTING PROBLEM WHEN ENGINE IS COLD.
- Check specific gravity of the battery and perform battery test.
- Check starter motor cranking speed. (required speed 250 rpm)
- Check alternator performance and health.
- Check engine oil viscosity. (recommended synthetic 5W20)
- Check cylinder compression. (COLD 190 psi or more)
If the warning lights do not come on and the car will not start, I would guess the key switch has failed or a major fuse is blown. I would check the fuses first, then for power at the key switch.
You could be right, it may not be the battery, but something to consider.
In cold weather the damand on the battery to turn and start the engine is much higher than in warm weather.
Often people buy a replacement battery without knowing what the minimum, "cold cranking amps," rating is for their car. And often there's no sign of any problem. But, when the weather turns cold not having the minimum cold cranking amps is now a problem.
Just as a procautionary measure, you could read the cold cranking amps rating on your battery, and then call any parts store to see what battery is called for as a replacement. This could prove very helpful.
Something else that may be helpful to you.
1. You could check on your battery to see if it is a maintenance free battery.
If it's not maintenance free, you should have the levels in your battery checked. If the levels are low it will prevent the alternator from charging the battery up to its peak level.
I am assuming this a cold weather only issue ?? Turn your key to on before cranking it over for about 5 sec to let the glow plug heat up a moment. Not allowing the glow plug to warm will wear out your starter.
