    Heres my post from another board

    Ok guys. Serious problem here. My truck is used 5 or 6 days a week to commute to school, and to work. So I kinda need to get this fixed.

    I went out to start it yesterday, and it wouldn't start. 14 degrees out.

    My dad and I pushed it into the garage and kicked the heater on, he said it started, but wouldn't start back up. I got home, started up, then it started RIGHT back up.

    So, I've come to the conclusion, it'll start right back up when its about 110 degree under the hood. But, It won't this this morning either. It's 37 degrees.

    I finally cranked it over long enough to get it to start, and then die. So I kept trying, and got it to start. But only after 2 mins worth of turning over?


    Can you guys solve my problem?! I would be terribly Happy, and thank you forever!

    Guess I got to tell you what engine and such.

    2000 S-10
    2.2 5 speed.
    40,167 miles.

    It threw these codes

    Ok, Guys

    I went to autozone and had them check the codes, it was throwing.

    Turns out its throwing these 3, in this order.
    1.P04019 Error- PCM has determined that a malfunction exsists in the secondary air injection system.
    2. P1137 Error- Lack of H02S switch - system indicates lean (My starting problem)
    3. P0410PD Error- PCM has determined that a malfunction exsists in the secondary air injection system.

    Try some air injection cleaner your injectors might have some debris in them. Its worth a shot and its cheap enough that if it isn't the problem you won't be out of alot of money.

    It sounds like the mixture is too lean on cold starts. I don't know your engine so I'm guessing here. I would suspect a bad "cold start valve". I have a VW van and I know it has a valve for this purpose and I would imagine all other vehicles would have something similar. It takes the place of a choke on fuel injected engines and injects more fuel when the engine is cold. A richer mixture is needed when the engine is cold. Get a manual for the vehicle and it will tell you where to find it on the engine and how to trouble shoot it. Good luck.

    I was assuming the battery was good and the engine was cranking over normally.

    Spray the throttle boby and clean the little air hole.

    If it were a carb I would say your choke is stuck open so Auto Zone is correct.

    I have had several trucks that run great in warmer weather but if it gets real cold its just hard to start or wont start at all. But warm them up enough and they start. Well you checked the codes and nothng really jumper out at you like something totaly failed. I leeds me to try changing the fule filter.A filter that is just a little cloged will work for years till it gets really cold then the will restrice the flow when cold and you get many of this type of error codes.
    Just my experence. good luck

    On a fuel injected engine like your 2.2 they do have a cold start enrichment system. This varies from engine to engine. Any competent shop can pull the AllData info on the engine and know where the cold start components are as well as their proper specifications for testing.

    Shouldn't be an expensive labor wise, but it might be pricey in parts. The major issue is that you can attempt to solve this yourself by guessing and throwing parts at it until you find the right one, or you could take it to a professional (I'd even go to a chevy dealership on this one), and they can have it taken care of in a few hours.

    possibly the rotor button...if that fails try changing the fluid in the turn signal....

    Yes, I have found the bumper terminal on my trucks sometimes needs turning. If that doesnt work, you can do what all the other dealers do now, and reflash the pcm, and call it fixed. :cool2:
