Have you tried the CPS?

You may also want to have a cyl. contribution test ran on it to check the injectors.

Welcome to the Forum!

I read on here that someone dropped a injector while on the road. Of course no access to scan tool so he pulled the valve covers and unplugged the injectors just for a moment while truck was running to determine which one it was. Just my 2c..
