Freelander 1 Fuel pump problem td4 2002

That's the intention pardec, the new seals should be with me by friday so I shall refit them and see how it goes. I am going to test the fuel pump relay to make sure its not "stuck open" first, but I don't hold out much hope for that.

Ok I've put the washers and gasket on the fuel pressure regulator and no joy. What next ? The hp fuel rail sensors again I guess ?

Its chase the rabbit time unless you can get the codes read. Could be High pressure fuel harness dicky, You could try a Injector leak off test and see if all the injectors performing correctly. When you replaced the LP fuel pump and filter. Were they new?

yes all brand new madmustang

Have you replaced the regulator

Not the regulator no, but ive replaced all the seals and gaskets on the regulator.

What about getting the codes read?
This is a good read if you want to understand the system more http://myweb.tiscali.co.uk/andymacs/media/AKTrainingCommonraildieselpresentation_000.pdf

Well after a long struggle I've managed to sort this out.
I replaced the fuel pressure rail sensor and it wasn't that so Ive just replaced maf and it's running beautifully.

You know I nearly said it was the MAF. Glad it got sorted and a lesson for use all. If you suspect the MAF, Unplug it and see what happens

Lol you are right. Lesson learnt

How much was the fuel pressure rail sensor and where did you get it?

It was about £30. It came from ebay.

Thanks

Just to revive my old thread, my engine management light has come on again !
So the last thing I done was change the maf sensor and this seemed to do the job, but obviously not.
What happens now is if I unplug the maf it runs properly again with no engine light on but I assume that's just because it's running on a default map.
Any ideas ? I think my only option is to get I plugged in and have the fault codes checked.

What did you replace it with? New or a second hand one? How does its connector look? Does it look good or does it look shagged?

i replaced it with a bosch maf. The wires looked fine on the connector. I even sprayed them with contact cleaner before fitting just to make sure.

Yes looks like you need the codes read other wise you are just chasing your tail.

Just been to the local garage and there card reader couldn't communicate with the td4. There bringing up there other diagnostic kit from there other garage on Monday, so fingers crossed I will know more then.
