My pressure gauge arrived with a bsp to M12 x 1.5 adaptor which allows it to fit the injector end of the fuel pipes or in place of the fuel rail pressure sensor. All good and in excess of 6,000 psi when cranking. Now with an injector out and...

I'm hoping a logical approach will not only be educational but also fruitful ! I have a feeling you might be right although I need to know how the injectors are fired and whether RAVE is correct. An alternative is to take voltage readings from...

I don't want to doubt RAVE but is this correct? Each injector has an electrical connector which provides a 12V direct supply from the main relay and connections to the ECM. If the battery voltage falls to between 6V and 9V, the operation of the...

While waiting for the high pressure gauge, decided to fit a spare HP pump. For info, no need to remove starter or coolant fitting, remove regulator so that you can get to the bottom nut, lift engine a bit with mount off and straightforward job...

OK. I'll leave business management to you both !! Too complex !

Post in thread 'T4 Testbook & cables?' https://www.landyzone.co.uk/land-rover/t4-testbook-cables.109463/post-1109567 Any help?? Hasn't been on here for a while though sadly.

To solve this and any further high pressure fuelling problems that come my way, I have purchased a 6,000 PSI gauge and an adaptor that will fit into the hp pressure sensor hole. This will allow rail monitoring. If low I can also fit the gauge to...

Do the ARB bushes while the drop links are off. Takes all load off then ! You'll need to slide under and a pair of ramps will help. 4 x 10mm bolt heads from memory threaded into front subframe.

Side lights on front interior light operate with switch push buttons. If that doesn't work clean contacts on pcb where plug fits.

Useful HP pump exploded diagram. Useful if, with all the springs in, it explodes !! https://injectionpumps.co.uk/interactive/interactive-bosch-CP1-parts-diagram.htm Not identical but similar...

Thanks, tested original and substitute in another vehicle as scope has broken !! So - I conclude. The HP pump is not providing any sign of pressure after cranking when rail nuts are opened, but the voltage on the HP sensor reads about 1.6V which...

Thanks. Yes did that ! Beginning to think it is a wiring rather than a component failure. Will be looking for key voltages. If it has ecu, crank and cam sensors and fuel it should run at least... Injectors are not firing but fuel is present...

Bit more progress. Wasn't convinced fuel was arriving at the cylinders. Hooked up an external injector with fuel line and electrics in a tray. Cranking revealed no spray at all. Hard to read fuel pressure when cranking as I think the feed to the...

There is this one available...

Thanks. Does a HP pump regulator problem throw a fault code?? Beginning to think that the pressure sensor is not telling the truth. No pressure on rail after cranking.

Checked out fuel rail sensor to ECU wiring, modified loom fitted and continuity checks out ok. Rather surprised that cracking an injector fuel nut immediately I stopped cranking didn't show residual pressure. May be a clue !

Got proven working set of injectors. They actually looked very new and well greased when inserted so obvs not originals. Cleaned, didn't disassemble as wanted to eliminate any risk of introducing another failure!! New seals and washers. Charged...

Swapping to a facelift scuttle solves the old broken rubber problem. The later ones have hard plastic right up to the ends.

All the dirty components will get the full treatment. All in the washer tub waiting. I have a spare set of manifold, egr etc clean and on shelf to reduce turn around times. Changed the cam cover this time also to prevent dirt going into the...

To fit the bearing you need to press it into the hub carrier by using force on the outer rim only. I can't see how you could do this. Also after fitting the bearing the FL1 has a circlip to hold it, think the FL2 is the same, not sure how you...

It has all been cleaned out, new filters and oil. Set of injectors to go in tomorrow from a spare working vehicle when the seals and washers arrive and then see what happens !!

OK it's official. Don't think vehicle has had an inlet clean, egr clean, oil change or filter change or air filter since it left LR all shiny new !! Have a look at these. The oil filter just fell apart. Wonder why it was overfuelling a bit...

Like this ?? https://www.ebay.co.uk/itm/370626186585?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=JyrFJ85kSiS&sssrc=4429486&ssuid=b5qQSb6hQNK&var=&widget_ver=artemis&media=COPY Except I see you want rear. But I don't see how you would press...

Thanks for the confirmation. Injectors are out and the egr is almost fully blocked. This would not help the fuelling!! Will post a photo. I think this is 140k of carbon. Never been off I bet. Updates later when I get to escape to workshop for a...

EV is plan Z. So a way to go !! Thanks for idea 🫢

Many thanks for the details. As I read the thread the HPFP was most likely not to blame is that correct ?? My plan is clean and fit 4 x 049 working injectors with new seals. Refill with fair but used oil and see what happens. If level goes up...

Thanks I did see that but wondered what the difference is. Also could they cause problems long term ??

The 2 x new looking injectors are neither part number: 0445110049 manual cars TD4 Or 0445110130 auto cars TD4. They are 0445110030 which appears to be from a Rover 75. Could this cause overfueling and so the diesel in oil problem?? If they...

How does that explain coolant in bore 1 I hear you ask !! Further inspection shows coolant is all over the top of the engine and so either the split sprayed it or the top was removed. Injector 1 was already out when I picked it up so it could...
