check the coolant temperature sensor. When this sensor goes bad, its resistance is too high signaling the engine control unit the temp is way colder than it really is so the computer flloods the combustion chambers while cranking the engine and so no start.

first remove the normal intake and then you have to completely take off the front bumper to fit it in there right, it's a total pain in the butt. i have to jimmy the intake in there because there was not a whole lot of space.

Hey, i had similar problem - not starting when wet or cold. Would turn over, but no go. Ended up changing distributor cap and rotor and first try she fired right up and no problem since. Keep spare cap and rotor handy now!!!!!!

You need to purchase the tool for removing the O2 sensor. It's a socket that has a slit down the side for the O2 sensor cable. This will cost you about 20-30$. The 02 sensor will un-screw with a socket wrench. Best done when car is cold. Otherwise you will burn your hands. Good luck.

A cold boot - is starting up the computer from 'dead'. A warm boot - is re-starting an already running computer.

Suspect a defective temperature sensor-- the one that talks to the car computer. It is not telling the computer it is cold outside, and not enough fuel is added to allow startup when cold. Suggest replace the temp sensor.

When a car is hot, keep the car running and add water to the radiator. When a car is cold, you can simply put the water into the radiator.

No - a cold boot is starting the computer by switching it on. Re-starting an already running computer is a 'warm boot'.

Most likely your alternator is starting to go bad, or your battery is starting to lose its charge in tge cold, which means its probably time to replace it.
