Freelander 1 TD4 Leak back test results. Thoughts?

flanagaj · Oct 19, 2015

I have just performed a leak back test on the TD4 and I wanted to gauge peoples thoughts. When I tun the ignition key but not crank the engine, I can see no diesel in the clear pipe connected to the leak back of the injector. If I crank the engine it does not start, and once again I only get a small amount of fuel in the leak back pipe of 2 injectors.

I have no diagnostic equipment to hand so am unable to test the pressure of the low / high side. Just wondering what test I could try next in a bid to diagnose the fault?

Thanks

your not getting fuel at the injectors work you way back until you find where you are getting fuel

I have just replaced the rear LP pump at a cost of £127, but battery is now flat so cannot really test. The new pump, however, does seem to sound much louder and sounds like it has more power than than the one I took off. Will trickle charge vehicle battery tonight and retry tomorrow am. Fingers crossed.

Without a diagnostic machine I am working blind.

Ooh. Now I am worried!

I replaced the fuel filter 5 weeks ago and I know that it was a Britpart one :-( I have just read this article regarding the Britpart filter collapsing and blocking the outlet port. I wonder if that's what has happened to mine.

I chose not to put a new filter in today when I changed the LP one as I found getting the filter out of the plastic mount a right pain.

Do others on here use Britpart fuel filters?

Ok. Tomorrow I will disconnect the LP fuel supply to the HP pump and see if the LP pump is getting fuel to it. If fuel is getting to the HP pump, how do I then test that?

I Hector's? Sorry, but you'll have to elaborate for me?

Ok. Thanks. I think I might concede defeat in this instance. Without pressure testing equipment you have no idea what is actually going on.
