    I just replaced the engine in my 95 taco (2rz, 2.4l) and after hooking up all the wiring and vacume lines etc I have a couple of problems. Firstly I used my original wiring harness, intake, injectors and distributor so I know they are all functional. so the problems...
    1)No spark
    2) blower fan stays on after ignition turned off (if turned off with the knob it doesnt come back on unless the ignition is turned to on)
    3)temp gauge gos all the way up after turning ignition off (it goes back down every time I turn the key on)
    So does anyone have any idea where I could have gone wrong with any or all of these issues? could I have missed one part of the wiring or do I have a more major problem? thanks in advance for any advice.

    Is your ECU properly grounded? Check all the grounds while you're at it.

    ...too much shit to list.
    Check all the plugs on the ECU and make sure they are fully clicked in or reseat them. I had one plug that wasn't plugged in all the way and I threw 8 different check engine lights after a motor swap of which none of them made any sense. 1 of the plugs on the ECU wasn't seated all the way.

    yup, what they said. Grounds are easy to miss, and a plug can look plugged in, but not be fully engaged.
