I have just gone through all
the steps ie replace injector and injector sleeve seals, replace oil with Penrite HPR5, replace both oil filters and finally new glowplugs (while receiving the Holden safety recall in the middle of all this!).
Problem is the mechanic is unable to get oil pressure into the common rail and therefore fire the injectors; does the changing of the second filter(the smaller one Holden originally said didn't need to be changed for the life of the motor) require some form of "bleeding'"to get the oil flowing?
I have also heard of a problem with a high pressure relief valve which has been known to stick open thus dumping oil into the sump rather than pressurising the rail.
Can anyone help?

Cant remember the exact details, but we often used to have problems with this type of fuel system on the smaller Caterpillar truck engines. They are very sensitive to the type of oil used and the oil level. Make sure teh fuel side of things is very
well bled, then crank for a bit longer. Caterpillar actually worked with Isuzu to develop the system used by Isuzu, so they are very similar.
Any more problems, I'd give William Adams P/L, Truck Service, at Clayton a ring, 03 9566 0675. They were very good with these systems (HEUI, Hydraulic Electronic Unit Injection). They ar eht Victorian Caterpillar Dealer and were working with these systems about three years before it came out in the Jackeroo

Must be a re-assembly thing.... wouldn't you love to have an Isuzu engineer working on it ? But no....here we are in Oz with a mob of
well meaning and obliging mechanics (if you are lucky) but most of them are feeling their way with this engine still ! I change the small filter every 10,000 k - it always self primes on start up - never been an issue. The valve you mention might
well be the issue.
I presume you are not getting the work done at a dealer - if, so.....good ! They seem to know least of all."This is a situation, up with which, we should no longer put ! (W. Churchill, on plans to reduce 4WD access in some parks).
