I know what it is , just thought it might help . my car stoped doing the test today for some reason , i mean the enj light comes on when i start it but never lights up on the test cycle like it should ... this just started like 15 mins ago .
 
Not to sound like the grammar nazi, but wtf is it lately with newbs who can't form a sentence or spell? When you do the KOEO test the car needs to be at operating temperature. As Mad said, go back. clear the codes- disconnect the battery for 20 minutes and turn the lights on- then reconnect the battery. Warm the car up then run the tests.

Report back what the results are and be polite and you'll be amazed at the help you will get.
 
got all new grounds , bat to frame one from passager frame side to enj and one from driver side enj to starter solenoid and frame and one from rear enj to fire wall. O bat is in the rear hatch , it is going to the frame back there also.
