Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I have replaced the suction control valve on the back of the high pressure pump for this concern.
There is a revised SCV available from Holden.
Can you check for any codes set please?
Is your engine a 4JJ1 or 4JH1?
Ok, yours is a 4JH1.
The fuel inlet banjo bolt is a fine porous filter.
The line where it goes onto the HIGH pressure pump.
Can you remove the banjo bolt and see how blocked it is?
It can be backflushed to clean it.
With no codes, it will be difficult.
But many don't know about this prefilter.
Yours could have a harness fault.
I've had one with a blocked cat convertor, straight off the turbo.
But that doesn't sound like your type of problem.
I would fit a fuel pressure gauge to monitor the low pressure pump.
The intank pumps are common for failure.
That's a good question.
I've never replaced one, but a mates Dad has.
I would contact the company you have mentioned to see if it can be replaced separately.
Can you see the banjo bolt filter in the photo?
The inlet fitting with the cardboard tube around it.
Have a good day.
It is starting to sound a little difficult now, because of what they say as well.
I would try the banjo filter, and a few other things like the solenoids on the RH guard for dirt blockage etc.
Have you removed the banjo filter to check for blockage as yet?
Or do you want to replace the pump assembly now?
I hope my advice has been of assistance to you.
Ok, I hope they will find your problem for not much cost.
Was there any codes?
Was it related to the immobilizer module?
Glad you have fixed your issue.
