    I have a 1989 Toyota pickup with a 3.0l that when engine is cold it is hard to start. Starter turns over fine ,but smells like its running rich till it warms up a bit. On warm days starts up and runs fine. Has no rough idle and runs smoothly. Just hard to start in the mornings. It chugging till it stays running on its on then clears up and throttle does nothing till it clears up. Smokes and smells rich till it warms up a bit then it goes away. Has new fuel pump and filter . clueless now please help.

    Most likely the temp. sensor has gone bad.
    Get You a repair manual, haines/chiltons is OK, check the book for testing procedures or, do a search on youtube, should be plenty of videos for testing.
    Also, you will need a multimeter, they can be had for cheap at walmart etc; be sure that it is a digital, an "analog meter can damage some computer, ECM, components, from the voltage of the batteries.

    Look at the injectors after you shut it off ..see if they are leaking fuel.

    Tested it like the manual says ,and it tested bad . Had my local parts store order temp sensor . I'm going ahead replacing the temp sensor and cold start injector . to be safe.
