Looking For OBD2 Help No communication

Ok , so , forgive me if im in the wrong place , and have ask a question thats been answered , but ive searched and havent found anything definitive to the OBD question.

I have a 2003 , zx3 2.0 zetech. Im in the USA , the sticker under my hood , says OBD2 Compliant (not certified) . Yet my connector wont communicate. Ive tried various softwares , none work. It does work on several other older and newer cars that are GM.

What connector does this sucker have? Is it EOBD? The pins populated are 2,4,5,7,10,13 & 16

Help PLZ! and THX!

BUMP

I have the same issue in my 2003 2.3L Duratec. I just got the car and I need this fixed to get the car smogged and registered. This is an old thread, but with a few more years and the cars getting older, has anyone else had this problem? Know the fix?

There is a few things , pins push out of the OBDII plug in is one , do you have ------- on the ODO ?

When you plug in the scanned does it power up if not check to make sure you have power and ground in the plug in

Could someone with a 2003 2.3L 5-speed post up a photo of their OBD2 Port?

Checked the ODB2 port and everything is in its place. What are the other possible senarios of why it's having communication problems?

Guessing you have an open circuit. Get multimeter and test wiring from OBD plug ->to-> PCM. Sorry, I do not have the wire diagram for the OBD system.

I checked my 2002 release of the Focus Wiring Diagrams, but strangely, there is not a single reference of OBD, OBDII, OBD2, or OBD-II in it!!?? What the *#@^!?? Maybe I will look again after lunch.
