Codes after installing injectors low voltage?

[jrex2506]

I just installed 155/30 injectors, running rough after 10 minutes of idling. Codes are p0264( #2 low voltage) p0273(#5 low voltage) and p0277(#6 high voltage)

Should i assume the injectors or harness? Checked ficm, its at 49 volts. Will use scan tool tomorrow to check each injector. Just getting an idea, or did i not run it enough to tell, only idled for ten minutes, no driving or anything.

Could it be air still clearing out from initial start up?

double check all 3 ficm plugs are fully seated, and all injectors are plugged in fully.

I checked all connections on the injectors and the ficm....

If ficm is good, all plugs are good, and codes were non existent before injector install, it's the injectors.

Ok what causes a low voltage in an injector?
