Car Will Not Go Into Diagnostic Mode
When I jumper the pins to put it into diagnostic mode nothing happens.
Anyone have an idea what this could be, is there a fuse that powers it.
BTW the car is a 1992 Camaro RS that I swapped an LB9 into, its speed density TPI
Any help would be appreciated.
Thanks!

Yes the SES light comes on when I first turn the key. Engine is off.

Did you move the wire from "E" over to "M" on the ALDL ?
It connects with the tan airbag wire on "M".

Dyno don,
I did not move anything on the ALDL. Do you now what color the wires that should be going to the A&B terminal should be?

I purchased a new ECM and that did not solve the problem.
I also tested the ALDL connector with a test light and A had power. Is this normal?

Blink is good, flashing is bad. The blink means that the ECM is running from the PROM, and not in limp mode.
