Hi Everyone,

I have a 1997 4Runner with 89K miles. I do most of the maintenance on my own and has been running perfectly.

So last week we had this Polar Vortex where temps. dipped below -50F with wind chills here in Chicago. I park my car outside and it was fine before the cold snap.

I tried starting the car next day when the temps were still below 0 and it didn't start. I let it sit since I have another car and didn't want to jump start in the cold weather. Today finally we are above freezing and i tired jumping but it wont start. It cranks but wont start. I checked the battery voltage which is 12.4 so the battery is still good (Toyota true start replaced 3 months ago).

I noticed there was moisture all over under the hood (battery, air filter cover, belts etc). I used the leaf blower to dry it and not sure where to start. I also added sea foam to the gas tank during the last fill, not sure if that did something.

Here are few things done:
Spark plugs, wires - 70K miles (at dealership)
Started -78K miles (at dealership)

Any suggestion where to start diagnosing the problem?

Thank You!
