    92 corolla
    I have a 92 toyota Corolla 4cyl. 16 valve engine (fuel injected) that is hard to start when cold it will crank and sputter until finally it will run. Once running it runs well I have already checked the circuit going to the cold start injector and seems fine so I checked the injector itself and no fuel so you would think great there's the problem bad injector but noooooooo, I finally the cold start injector it may seem a little better but it is still not right any thoughts??

    Where to begin? There are several possibilities. How many mile? Have you replaced dthe fuel filter? Properly cleaned the injectors? Cleaned the throttlebody? It could be the coolant temp sensor failing. The sensor could be goinig out of range. It also needs proper coolant on is. Check the coolant condition and level. Good luck and let us know.

    A lot of people deal with this on the older camry's too. Most think fuel related when it's actually spark related. The secondary coil resistance may be breaking down on cold start up's when enrichment is needed. I've replaced enough of them to go with that idea.
    Easy enough. But I do recommend a dealer part though.

    I would focus on the Ignition Module (ignitor), which is expensive for that car, and the coil. See if your local AutoZone store can test these components for you. They don't charge for this service. 90% of these type of problems are electrical-related, not fuel.
