Why is my DT 466 getting hard to start?

The 466 uses oil to hydraulicly actuate your injectors. Once the o-rings start to leak, the high pressure pump has a hard time building pressure to actuate the injectors. Sometimes it takes 30 seconds to finally build enough pressure to start. This is about a 2 hour job at a dealer. Did you check ALL fluids accurately?
