ran injector leak test. fuel pressure measured is on the right and on the second log i enlarged only that column.

did 3 separate logs
it has the old style fuel pump and the paint on the bolts have never been touched.
cylinder performance test shutting all off except one -seemed cylinder number 4 was a lil different, all others felt good. engine seems to have an extended crank sometimes. engine doesnt run-on at all when shut off so i'm assuming to injectors are ok? looks like the pump is on its way out. my question is will i have these dpf regen issues with a high pressure pump thats on its way out or am i missing something else in the dpf system, ie. exhaust leak, leaking exhaust valve guide seals or skewed pressure or temp sensor in dpf.
thanks in advance for your guys help really appreciate it! special thanks to rawze for creating this wonderful place.
im hear to learn but also know info comes at a cost, im willing to pay to pick your brains so send me a message.
