2000 chevy S10 will not start if weather is cold and raining. Electrical system has been checked by mechanic and could not be reproduced in the shop. I checked the IAT and found a the resistance to be 4300 ohms when cold and 930 ohms when heated with a hair dryer. Reference voltage is +5 volts. This only occurs when the weather is cold and raining. What else should I check?
