Fule pressure measured - Dididadzz - 11-11-2024

I connect onsite an fuel pressure was saying -1 when key is in the on position
On cranking it came up to 250 an start
Could it be lift pum going out
It starts rough in the Morning but then smooths out

.
Is this a common rail enigne?.. or an older with an IFSM?> .. its anyone';s guess.

no one here has engine ESP. .. What make.model engine?. ser#?. mileage?. Some history/maintenance history? .. and is there any other problems?.


BTW: rough idle can be a million things including the head itself simply wearing out.

Does it lope hard when cold for a minute or two then smooth out? If thats the case, most of the time one of the fueling actuators are the issue. Try swap them with a good used set and see what happens!

re-run the overhead valve adjustment and do an injector leak test on it.../
