I have a 2000 BLuebird body, GM chassis with a cat 3126 engine and I have just replaced the injectors and not the service engine soon light is one. Anyone know how I can pull the codes? I don't have diagnostics for cat.
Found and corrected the problem, light is out. # 6 injector harness wasn't in correctly. Found that with a temperature gun, however I would still light to know how to get the flash codes.
