I've tried searching all over the forums but I can't find an answer. Ever since I got the car it has been running a little sluggish, as if I'm loosing a whole lot of power. My problem is that I've tried to plug in an OBD2 ECU checker, but it displays "please connect" when its plugged right in. I really need to run a diagnostic so I can know whats wrong but it doesn't register the checker.

I drive a 98 Z28
Mods: (all work done by previous owner)
SLP Lid
Hand Ported Throttle body
MSD Ignition Coil Wires
Unknown Cat-Back
MAF Screen Popped off
Throttle body coolant by pass.
(pretty much every imaginable free-mod)
And what I expect to be some gear work...



Can anyone help me please?

Pics of the Pin pluggin.



This is the only diagram that I've managed to dig up from here.



By the looks of it, I have an extra pin on port 9, is that normal? Or do I have to check if the pins/wires are in the correct location?

 

Check your fuses.

 

Yes, check the cigarete lighter fuse, it also powers the OBD-2 port

Check for 12V on the Pin #16 (lower right on your photo)

 

Just found the cigarette lighter fuse blown.... I'll replace it asap and tell you guys how it goes. Thanks for the help!
