I threw the CEL the other day and i drive over to my work to get the OBD II computer scanner that we have.  I plug in the unit and it wont turn on so i figure the unit must have a problem, my boss dissagrees and tells me that my port might be the problem.  I drive over the autozone and borrow there code reader and the same thing happens.  I checked all the wires coming into the terminal and all seem fine.  I'm just confused as to why this wont work for me when it worked fine a couple weeks ago when i threw the CEL for my evap system.  I'm 99% sure its the evap again since the last code it threw was a 440(evap system malfunction or something like that).  
The car is a 2001 cavalier 2200.
any ideas?
 
Check all your fuses. it sounds like one may have blown.
 
 
i forget which fuse it is
 
 
thanks, i'll check that a little later and see how that works....i'll post sometime tomorrow to let you know the results.
But if it was the fuse....would it be related to the PCM fuse?  if i did blow the PCM fuse wouldnt i have had many other issues to worry about?
 
no, it would just blow the fuse that powers up the scanner, I think it maybe the horn fuse or cigerate ligher fuse,.... just check them all with a test light.

i have alldata i will check and post
 
 
 
it is gonna be the cigg fuse. it islocated in the fuse block under the hood and it will be a yellow 20 amp fuse. 
Hope that helps you out man. PEACE!
 
 
thanks, i'll check all the fuses out anyways...but thanks for pointing me in the right direction.
 
it ain't a problem, man. i'm just sitting here at work bored out of my mind waiting for my phone to ring (i work in a call center for an extended warranty company)
 
 
Ok.  One new 20 amp mini fuse later, and i'm back up and running with a functional port.  Strange how that port shares the same power supply as the cig lighter...
 
all it is is a generic 20amp, 12 volt line, its just inlien with your cig lighter, thats why they do it
