@V6I performed the test by loosening the injector pipes on the injectors and turned the engine slightly and then pumping the priming bulb to see if there is fuel coming from the pipes.

@GrumpyGel I removed the belt that was on and took it as a sample to get a replacement one, not sure on the amount of teeth on it will have to check. My apologies the pump is a refurbished one that I purchased at a fairly good price. I did set the timing of the engine and checked that no1 cylinder was at tdc and that the lines in the plastic cover and the crankcase gear was aligned and I could fit the locking pin to the flywheel. The pump was locked in place when I received it, once installed I placed the locking pin in place before I tightened the pulley and then released the bolt securing the shaft. Then I followed the procedure on torquing the tension pulley and the flywheel. I did not change the ECU at all.

That will be low pressure leak through coming out of all the pipes at the same time. That is not enough pressure to open the injector nozzle.

Can someone supply me a picture of the injection pump displaying which injector is connected to which port on the pump. I just want to make sure that I have connected them correctly after the pump replacement.

I don't know if it makes any difference Tony, but the L Series is not a common rail engine. The pump 'in theory' will supply fuel down each of the 4 pipes to the injectors consecutively (ie its not 1 shared pipe that splits for each injector).

The pump will only pump fuel to the cylinders if electronically enabled by the ECU (ie ignition on, not immobilised and possibly in a crank/running state). I don't know how the pump stops pumping when not enabled - it may just 'open all valves' so pressure can't build. In this state its quite feasible that if fuel is pumped by hand through the system - it may result in fuel being expelled via multiple injector pipes.

So, I'm not sure how much you can tell by pushing fuel through using the hand pump. Someone else may have a better idea - but without that knowledge, I don't think you can come to any conclusions.

I don't think I have any pictures that will give enough detail. Even with the acoustic cover off, the plenum chamber is likely to hide the pipework entering the fuel pump. Its late here now - but if you haven't had any responses by tomorrow I'll take some pictures in daylight.

Hi GrumpyGel. Thank you. I do not have a plenum chamber installed. If you look at the fuel pump from the front you have 4 connectors. Mine is connected as follows

Top right is Injector 1
Top Left is Injector 2
Bottom Right is Injector 3
Bottom Left is Injector 4

Sorry discard my last regarding the plenum chamber.

Yep, got that. But the low pressure side of the pump bleeds through to the injectors, this keeps air out and helps lubrication. So if you take the injector pipes off and get LP pressure up (with the primer or electric pump) a little fluid should come out the pipes without the engine turning.

The injector connections to the pump are as you describe - thb, with the metal pipework, I'd have thought it difficult to connect them up any other way.

I've just looked at Rave - the leak back pipes go via the pump to the tank - I wouldn't mind betting that when the pump is disabled it will pump into this leak back system.

Looking at this picture, it looks like I should push that leak back hose on injector 2 on a bit more!

GrumpyGel · Feb 1, 2017

The refurbished pump you got was a VP37 for Freelander not a VP37 for Rover cars? They are different.

Nodge68 · Feb 1, 2017

I'd still be putting the original pump back on. I have a philosophy of. It's not broken, don't fix it.

michael_v · Feb 2, 2017

Thank you for the photo, that confirms that the connections are correct, the leak back hoses are connected to the pump to feedback to the tank. Yes the fuel pump is the same model as that on the freelander. Still waiting for my service kit for the starter so not much happening besides cleaning of dust and oil off everything.

Here is a couple of photos. Enjoy.

What she looked like before I washed and started cleaning her.

Stood in a shed for 3 years

Don't see many 3 door L Series - that looks to be in great nick body wise and interior.

Did you jet-wash the engine after you had it running? Wondering if some water has got into some electrics.

michael_v · Feb 2, 2017

She is good nick body and interior, there is quite a couple of 3 door L series in SA, did wash her but closed the electrics before I did, she ran after I washed the engine.

michael_v · Feb 2, 2017

Looked at a 3 door K series petrol, too much work was required on this one engine and body wise, has been standing after a head gasket failure.

Gotta love a cylinder head in the footwell.
