Sorry, yes - take the nut right off. You may need to put the car in gear and handbrake on to stop the whole lot turning.
its an automatic hopefully park will do it.thanks for the advice i am not a trained mechanic but sort of self taught thought i knew it all till i bought the freelander its like triggers brush from fools and horse best one he ever had itd only had two new heads and three shanks lol:).
 
right now i am ****ed off put hp pump on still not firing would it start if the fuel rail pressure sensor was buggerd?
 
Done a few drain offs ( breakdown recovery tech ) they can take some starting after a drain, you can use pocket rocket ( spray oil ) or similar to get them running long enough to get pressure up, or tow to start but yours is a auto so can't do that, once they're running keep it running for a good while or can air lock again, good luck
 
i suppose i could try jumping it off a tractor at work plenty of power should help there is plenty of fuel at the rail just not high enough pressure when you crack the 1st injector pipe there a good flow ive also changed regulator seals.

How many times did you let the LP pump prime? Do this 2-3 times. I know you have fuel to the injector unions but there still might be an airlock. We're talking thousands of psi here. Watch out for high-pressure diesel though - gloves and goggles.

If no go it might be worth pulling the injector pipes in case there's bits of O-ring blocking things.

It's possible the petrol has buggered the injectors too.

EDIT: Are we sure the LP pump is okay?
 
I feel your pain. I put petrol in a td5 and ended up with a very expensive bill.
New fuel pump, filters, frp and all kinds to get it right again

i will try that tomorow would a faulty fuel rail pressure sensor stop it from creating high pressure getting close to scrapping it.
 
I was going to post a couple of days ago, get some easy start. remove the air filter and get someone to turn it over and start it on easy start. keep it running on easy start and hopefully it will drag the airlock through
 
i will try that i am going to fit a new fuel rail pressure sensor and a new cam sensor tomorow in theory if the fuel rail pressure sensor was duff due to the contamination it wouldnt allow the hp pump to produce enough pressure anyone any thoughts on this.
 
shame you dont live closer, me and a mate always had the same car.
in situations like this we uaed to swap parts from car to car. put a senser from the poorly car onto the other till the fault transfered.

well ive just been reading diesel bobs page wich says do a pressurised bleed through could this be acheived by using an airline and rag at the filler whils someone turns it over.

I suppose, but the Td4 system is meant to be self-bleeding. Worth a try, however I can only imagine it will bleed the LP side of the system.

If the rail pressure sensor is giving a 'high' signal it could be disabling the HP pump output as you say. I don't see how the sensor could have been damaged - it's mainly moving parts that get trashed - but anything's possible.

i am assuming there is a diaphram inside it that the petrol may have deterioated hopefully.
