    I have a 1996 Tacoma 137,000 miles 5 spd. 4 cyl. I just bought the truck yesterday and I have discovered that after the truck warms up just a little it becomes real hard to start. I have to hold the key in start for a very long time engine spinning and then it starts to come alive very slowly and then it starts, and then it run's very good. I let it set over night and all day in the hot sun, and it started right up no problem what so ever. I then drove it about two blocks turned engine off and it did it again. I gave it a little starter fluid but that did not help at all, I think its not getting spark.
    Can anyone help me out!!

    Thanks

    It could be a number of things. Has it been a while since the last good tune up?

    what all has been done lately?? sounds like one of two things for me...........either the iac valve needs cleaned/replaced...or the tb needs to be cleaned.

    I had this problem on a 96 2.4l. I don't know the exact way it's explained, but it wasn't using all of the gas fumes in the throttle body when I shut the truck off. Then it would be partially "flooded" when I went to start it before the fumes escaped. Cleaning the throttle body/ intake manifold and changing the spark plugs fixed mine.

    What’s the best way to go about cleaning the TB, and what/where is the IAC valve?

    I just bought the truck so not to sure about what’s been done to it. The seller told me they just put a fuel filter, air filter, and oil change. I called him back today and he did admit that this has been a problem for a few months now.
    I think I'll go buy some tune up parts for it plugs, wires and cap. Is there anything else I should get at this point?

    Be sure not to depress the accelerator when starting. The couple of times I spaced out and did "give it gas" it made the truck more difficult to start. This is when the engine was at operating temps already.

    Put a meter on your coolant temp sensor. Check the readings cold and hot. No change=bad sensor. Same can be said for the intake air temp sensor.
