Help, Cant access ECM
Car will not run with out something plugged into the obdII connector
With a code scanner in the car runs fine, just gives one code 122 which won't erase...
Have tried to get into the computer via HPTuners and it wont connect.
Anyone had these problems? How can i fix this?

when you say won't run without something plugged into the connector? cranks, but no fire.
I have heard of a car with a ground wire issue, that woudl get a ground from the OBD2 port for the PCM with a scan tool connected to the device. Many OBD2 connectors jumper pin 4 and 5 together, this could be part of the issue of why it only runs.

will turn over but wont pulse the injectors or turn on the fuel pump
The gage lights won't even come on, the only thing that shows up is
Security but goes away after a few seconds
Bright Lights symbol
the radio comes on
and the fans will come on when the motor is a little warm
