dt466e injector removal

Time-lapsed removing the injectors to replace the Orings had a fault code 333. replaced the icp sensor no fix. ipr valve was good. so figured I'd dig into the injectors and found my problem.
I didn't go into detail with what I was doing I'm not a professional. so just a time-lapse of the removal.
