I got to two codes popping up p2155 which is Injector Positive Voltage Control Circuit Group 4 and p2149 Injector Positive Voltage Control Circuit Group 2. Any ideas to fix it. It keeps shut off the car causing not to start then I clear the codes, it fire right no problem. Runs for a few days then the car dies again.

 

Sounds like injector harness or injectors. I have a spare harness and some injectors.

 

I am sending the injectors out to get clean and tested. So Ill know if it is the injectors or not. I am going to test the harness later today with my test light.

 

The injectors are good. It Looks like the ecu.
