    1992 Toyota Truck cold start problem

    1992 4x4 22r, efi, won't start when its really cold outside. It cranks fine when its warm out, even it has sat for days. On cold mornings it turns over fine, may even act like its going to start, but won't. I can crack open the air filter canister, spray a little either at the edge and it will crank up fine, idle fine and crank the rest of the day. The next morning if its cold out, the same thing. Help! Thanks.

    Check your cold start injector.
    When was the last time you ran some injector cleaner through the tank?

    cold start injector

    How do I check the cold start injector and where is it located? I ran injector cleaner through it a few months ago.

    Looks like it's time to buy you a repair manual, Chilton and or Haynes.

    The cold start injector is mounted to the upper air intake manifold just above the level of the valve cover. It's more likely that the cold start switch or it's connector has gone bad. At this point you really do need a service manual to correctly troubleshoot this circuit.

    Many cars doesn't start in cold days, but in Asia where less cold cars starts easily. I have Toyota Tundra 2008 model and sometime it creates problem to start.
