Fuel injector Circuit low input cylinders 1,3, & 5
Hey guys, I have an 05 CTS 3.6 ... It'* throwing p0273 p0267 p0261 p0300 p0301 p0305 p0303.. I'm not familiar with these cars.. is this a common issue? I'm pretty sure it'* going to be a connector or the ficm is bad. I doubt it'* the ficm BC it'* only three and they're all on the same side all wired together.. any input or advice would be appreciated. It'* running horrible. Shuddering at idle no power etc..

ficm?
While the injectors are individually grounded by the ECM, they share one fuse for each bank.....
Did this just start? If so, I doubt that three injectors would go bad at the same time.....what I would be looking at is a wiring problem, possibly a chafed harness, or bad male/female connection in the harness connector(C121)......
There are numerous bulletins for clogged injectors, but to have them all in one bank tends to make me think it is more a wiring problem....
