ok psssst try this for me...
take you multimeter out to your car, and disconnect the clip to the coilpack... now put the red lead into the middle wire and ground the black lead to the car... put the key in the run postion, the middle wire should read 12 volts, or close.
then take a test light and insert it into one of the other two outside wires, making sure to ground out the test light wire to the car... then have someone try to start the car you should see the light flashing at a steady rate while the car is trying to turn over... make sure you test both of the outside wires...
If you do not have a flashing light or 12 volts then go to your pcm if you have a....
95 test pin 1 and 21 with your test light this is where the wires you just tested at the coil pack connect to the pcm see if anything changes... then check pin 11 to see if there is 12 volts.
If you have a....
96-99 test pin 2 and 3 with the test light, and i cant figure out what the 12 volt feed is on the harness... sorry. but you will be testing the left plug in your pcm.
do that and see what is up...

a test light will work ether way.If your useing a volt meter the voltage will read negitive if the polarity is switched.
