Hi, I am working on an 01 sportage and its only firing on 2 cylinders. #2 and 3. I hooked up a test light to the coil for the # 1 and 4 and nothing. So I connected my test light to the connector and I have blinking at the connector but not through the coil. Also I have 12 volts with the key on at 3 of the 4 connectors. The other has really high voltage showing. I know that both coils are good. Can the computer be bad? Please help.

Hello .. thanks for the donation .. much appreciated

If I am reading your post correctly .. you have no output from coil to #1 and #4 .. but you disconnected the plug to the coil from the PCM and tested, and got a pulsed signal ... if you are getting a pulsed signal to the coil .. but not out of coil to the plugs .. then the coil is BAD !! how are you sure the coils are good .. let me know

Responding to your email, I hooked up the coil that I thought was bad, to the 2 adn 3 cylinders, and it worked all the way through. Today I changed the computer out with one from a junk yard, and the car started up right away, no codes, and fires on all 4 cylinders.
