[Engine] No Fuel to Injectors
#1
Hi Guys,

I have just removed my injectors and replaced the seals (top and bottom) and spacers as they were all leaking. I've reassembled everything and bled the system by removing the fuel return pipe and pumping the prime pump by hand until diesel came through, however, the van wont start? I've loosened the injector fuel feed pipes and there is no fuel reaching the injectors? Is there another or better way to bleed? or could there be another reason why fuel isn't reaching the injectors? 

Thanks guys!! Huh Huh Huh

They can be a bigger to bleed have a go with pressing the primer bulb untill it goes hard.

I would guess that this is nothing more than air in the system, when you disconnect anything the fuel runs back to the tank.

As polar has said they can be hard to bleed through, lots of priming is required.

Try squirting easy start or carb cleaner into the intake as you turn the engine over to get it to start.

Hi Polar and thanks for your reply!

I had actually thought it was the primer bulb I was using which is situated on top of the engine slightly under the bulk head area?

Hi guys and thanks for the replies!

So am I correct to say I'm using the correct method of priming? remove the fuel return pipe and continue to pump the hand primer located on top of the engine slightly under the bulk head? Is it wise to loosen an injector feed pipe and pump until fuel reaches the injectors? at the moment no fuel is reaching the injectors

Hi jj9 and thanks for your reply! 

I'm presuming that once its primed properly, there should be diesel coming from the injector feed pipes?  Huh

Use easy start as a last resort, it makes a bigger bang than diesel so needs to be used sparingly.
I've just changed my fuel filter and primed via the rubber bulb that sits on top of the head on my M59 1.6. I had all the pipes connected and it took quite a while for the gurgling to die down. I think the resistance to squeezing the bulb will also be a tell tale.

Morning cancunia and thanks for the reply!

Ok, I guess I'll need to give it another go Today, but yesterday I really persevered and pumped it up several times to the point that the bulb was difficult to compress and still no fuel to the injector pipes Confused  I'm thinking maybe just as well replacing the fuel filter Today before I begin, since I'm having so much difficulty and going to need to really make an effort to get rid of any air blocks Huh

Reconnect all the pipework make sure the fuel filter is full = remove and fill if nesessary then press the bulb (a lot) untill hard then try and start keep repumping the bulb untill it starts.

If you're replacing the filter anyway, I'd do that first if at all possible. I was surprised at the amount of fuel that came out of my filter so be ready with a container.
