I'm after a Bosch diesel pump with numbers 0407 504 011 for my Omega 2.0 Dti. Just fitted newish engine with diesel pump 0407 504 004, But it won't fire up it just turns over and over. Or have you got any advice what the problem might be.

maybe totally off the mark here but thought the imobiliser is located in the top part of the pump
remember when i changed an engine on a bmw had to swap the top housing over

It's got to be the same number IIRC.
Pretty sure that you can't mix the pumps.

Whats the IIRC

If I Remember Correctly!
It might be worth asking the diesel pump question on the Frontera Owners forum as they have quite a bit of knowledge on the unit.

Hi There,
There is a lot of conflicting information about these pumps (Bosch VP44 series) on the internet and whether they are interchangable. The 003 and 004 seem to be interchangeable and likewise the 009 and 016 are for the 2.2. The difference supposedly is on emissions and the different catalyst setups on different cars. I'm not sure about the 011 but as it's a similar setup to the Vectra I'd be surprised if it wouldn't even run with an 004.
My understanding is that the 003, 004, 009, 011 and 016 are not coded and you should have a separate ECU (which IS coded) in the box behind the battery. This changed in 2002 with the introduction of the (confusingly named) PSG16 pumps which have the engine ECU built into the pump.
I can tell you from bitter experience that these pumps take some cranking over if they haven't been primed!! I'm not familiar with the setup on the 2.0 DTi but the 2.2 has a rubber link pipe with a jubilee clip on the return line above the diesel filter where you can 'suck' the diesel through but ensure that the ignition is switched on as you do this so that the stop soloniod is open and is allowing fuel through the pump.
Aside from the priming issue just check your connections and sensors such as the crank sensor have been reconnected correctly.
Just one final 'observation': your pump code should start 0 470 (not 407). Not nit-picking but it might help you locate the right parts when searching the interweb.
I share your pain having just gone through a pump change myself. Getting consistant advice from anyone about these was the worst part of getting it sorted. If you're anywhere near Reading I can recommend a good diesel specialist.

You will need to get the pump re-programed to the new car.
The fuel pump is now programed to the ecu and imobiliser so this will need updating. :y

There is a good mod that you can do that will help no end when you change the fuel filter and need to prime the fuel line again. Buy one of these, cut the fuel line and add it in....

Pump the fuel through before trying to turn the engine over. :y
