1996 Chevy S-10 4 cyl All Wheel Drive 104000 miles

I am having problems with starting my truck. When it is cold in the morning it won't start but if I wait until the sun comes out and hit my truck and warms it by the afternoon it will start right up. What could be the problem? The mechanics I have taken it to don't seem to know because it is always running good when I take it in.
Do you
have the same problem?

Every thing I am finding is that you need to check the coolant temp sensor here is how along with the removal and install for the sensor also when was the last time the battery was changed

The coolant temperature sender changes resistance as the coolant temperature increases and decreases.
Testing

Remove the sender from the vehicle.
Place the sender in a container of water.
Connect one lead of a ohmmeter to the sender terminal and the other lead to the sender body.
Place a thermometer in the container of water and heat the water.
When the water is cool the resistance should be high. As the water temperature increases the resistance should decrease smoothly.
If not, the sender is probably faulty.

Disconnect the negative battery cable.
Drain the engine cooling system to a level below the sensor.
Release the locktab and disengage the sensor connector.
Using a special sensor tool or a deep 12-point socket, loosen the sensor, then carefully unthread and remove it from the engine.
To install:
Thread the sensor into the engine by hand, then tighten using the socket or tool. and snugg tight
