Hard starts and check engine light

So my truck has been getting hard to start the past few days and then yesterday on my way home from the gym the check engine light came on. I checked the codes and there were two of them. One was low voltage on injector circuit #3 and the other was low voltage on injector circuit #8. Does this sound like faulty injectors of does it sound like a bad FICM? Or something else?

Thanks for any info!

Sounds like a bad FICM. If you clear the codes, you'll probably find that they come back, but for different injectors... further indicating that there is an issue with the FICM.
