Sorry

Engine turns over perfectly, all lights on the dash are correct, glow plugs were changed last year.

I would agree, also check the injector leak off pipes.

I have now run out of ideas! The actuator works, fuel is getting to the pump but it appears no further. I have cracked an injector nut loose and cranked the engine but there appears to be no fuel getting to the injector.

Does this mean the pump is history ( and unfortunately therefore, the car!)

Many thanks

Thanks for the reply... I don't think it is the pump either but just can't figure it out. It sounds like there is some air in the filter housing so we have removed the actuator solenoid from the injection pump and flushed the system through using the priming pump. Fuel comes out of the actuator hole. The actuator appears to be working fine. We have then checked to see if fuel is getting to the injectors but it is not.

In my very amateur opinion, this would lead me to a problem with the fuel not getting through the injection pump (Delphi r8448b182c)

Other forums have suggested a split in the fuel pipe causing air to get into the system. This would explain the air sound in the filter housing but surely fuel should still get to the injectors - we loosened off the first one, turned over the engine, but no fuel showed around the loose injector.

What can anyone suggest? £20 plus 4 hours garage time is going to make this close to a waste of cash on a 2001 estate!

Thanks

The solenoid is a sealed unit and impossible to get into unfortunately. I will try the fuel pipe and see if I can bypass the pipe completely from the tank to the filter. We have had the unit out of the tank but this looks just like a sender unit for the fue guage rarther than a low pressure lift pump - thought this might be the problem as suggested on some forums - however, it does not look as though it has any pump in it.

Thanks

Hi

Firstly many thanks for all your advice - I am an amatuer as you can tell but at present I am working with a local mechanic (for beer!!) to get this sorted as cheaply as possible.

There is a clear hose already running from the inlet to the filter but no air appears to be being drawn in. I have also put diesel in a pressurised container and attached that directly to the pump inlet. Again fuel is getting into the pump but when under presure it is not getting as far as the leak off pipe to start with. I can t remember but think we had fuel coming from the leak off when the negine was turned over.

Also at the same time we have cracked off an injector nut, turned the engine over and still no fuel is reaching it when the engine is turned over. So, fuel is reaching the pump but not getting through it.. We are therefore pretty sure tht the fuel is running clear into the pump, without air locks but just not getting through.

If it is the pump, from your diagnostic, do i have to stik to the same model number pump or are they fairly interchangeable with slight variations?

Thank you again

Yes. This was changeed last week as a first off. They appear to be tricky to test but when we removed it and turned the engine over, it is spurting fuel so I would assume it is working. Initially when we fitted it as a rplacement, the car kicked into life first time and ran well for a day of testing but then the next morning, back to cranking only
