Fuel Issues with 3ltr 4JJ1 Common Rail Isusu Rodeo Motor

This post is to all that may be looking into this type of issue.

I have put 103000k on the 2007 Rodeo now and have had a fuel issue on 3 occasions. Holden said they had an issue with this part and it got modified for the latter models.

The part in the limelight is Fuel Pressure Regulator (Part # 898145450 priced at $157.60)

First in the Simpson while in a bog the engine went into limp mode and the check engine light came on. The engine changes tone (rattles more and you can only get 1500rom max) and acceleration is not possible. After a few attempts it fired up and no more issues. The engine light was out the next morning when I started up.

It happened again just as i was parking up one night and the following morning took a couple of attempts to start it. It soon came good and the check engine light did not stay on for long.

This time the engine lost power at highway cruise and as I was slowing down the check engine light came on, it took a while but it fired up. I got into town where it happened just down from the Holden dealer and I was able to limp in to get it checked. This time it logged the fault which was the above part.

Apparently the old one has a smaller bleed hole and got blocked easily? The improved version will not do this? One can only hope :-)

The cause of my issue may have been some bad fuel, as I have also replaced the in tank fuel pump. I have the car serviced regularly and one fuel filter had suffered a lot of contamination.

At least it is an easy part to replace.

I have been told if you damage an injector they are $1500 each....Ouch
