Hi guys I wonder if anybody with a 3.6 Tdv8 and a iid would be so kind as to help me by posting a log of there fuel rail pressure readings during start up as I'm at a loss as to a fault I've being having and would love to see some for comparison,
I must be honest tho it isn't for my FF as that's a Td6 it's for my rrs but I hope that won't put anyone off helping me out as I have tried over there but I don't think they can handle the cold lol
Cheers in advance

Nobody?? Thanks anyway

I have the car but don't have the diagnostic gadget i'm afraid. If there is an app that will work with a normal bluetooth OBDII scanner i can do it for you.

try maybe posting here,https://www.aulro.com/afvb/l320-range-rover-sport/
lots of sport owners.

I will have a look on mine for you and post the results!

Does this give you the info you need??

That's exactly it brilliant thanks, I will try and figure out how to post mine like that,
your idle pressure is the same as mine but yours climbs alot steeper than
mine during cranking mine curves off at around 14kpa before it fires and
then peaks like yours

Glad I could assist with the data for you. As for assisting with the fault not sure I can offer too much assitance there. I assume that you havent had any codes come up on the IID tool? Also is there plenty of fuel in the tank and has it has the fuel filter changed recently? Outside of that there could be a leak or issue with the high pressure fuel pump.

Keep us posted on it.

It's been a long road with a few curve balls thrown in for good measure e.g it starts instantly hot or cold if a booster is attached which led me down a path of earths,battery & starter etc but now I'm fairly certain it's injector related or like you said the hp pump I did have rubbish low side fuel pressure so the tank has been down cleaned and pump module replaced and the filter which did resolve the hesitation and most of the codes, I'm just left with p0191 which is a rail pressure fault that incidentally doesn't throw up when boosted. Thanks again for the log

Whats your battery voltage while cranking? if your battery is tired and the voltage drops below 9.6v it will cause all sorts of issues, the electronics tend to throw in the towel at that voltage.. 2018 L405 Autobiograpghy
----------------------------------

Hi the battery voltage was dropping to around 10.1v cranking and because of the situation with the booster even though the car spun over fast enough I replaced the battery just in case but it made no difference, I'm hoping to get the injectors checked next week so hopefully that will be the answer, I'm just hoping it's only a couple as I don't fancy doing 8 in one hit

Just a quick update, it looks like I need 4 new injectors and will update when they're done with the new data

Nice work glad its all sorted and i could be some small help! Atleast it was only 4 rather than 8 injectors i suppose!
