Hi Guy's, my 4.4TDV8 l322 has just been diagnosed as the high pressure fuel pump failure. What I want to know is that what are the chances of it knackering the injectors in the process? Also, if I decided to fit a new pump, how are they timed to the engine?? Many thanks in advance Ash

I've managed to have a bit of a play today & noticed that when I do a network test, some of the modules don't seem to be working (unless someone can correct me).. Can anyone give me any more of an idea from the network test & photo's (Network test is here: ) Thanks in advance

aI've Still got this problem where my 4.4 tdv8 wont start, I've managed to get a couple of hours on it over the weekend & hopefully someone can help me.. I've disconnected all 3 sensors (on the pump, on the left hand rail at the back & on the front of the right rail). I did a re-read of the...

Ok, can anyone tell me what the live data should read on the pressure sensor live data with it hanging loose?, what im thinking is, to read the live data (which has been 17mpa) and start unplugging fuses from the engine bay & cabin, & see if I get any change in the pressure sensor the eliminate...

Everything was working fine, Already had a real good look at the loom, Is there any way that I can test the crank position sensor using live data as I remember playing around with the live data and one said crank & when I was turning it over, it said "no"?? Thanks

I was driving as normal (very wet roads, but no floods), and it just cut out (Just as if id turned the key off & rolled to a standstill). I will put it on charge in the morning, but welcome any other advice/pointers Thanks

Cleared the faults, disconnected the pressure sensor, tried to start it (only turned over a couple of times before the battery went flat) and the P0A94 dosnt seem to of reappeared.. So what does that tell me? Thanks

Right, ive unplugged the pressure sensor & on live data it's showing 220 mpa, the fault code is: P0193 (Fuel rail pressure sensor high input. Also noticed scrolling down that I also have P040D (Exhaust gas recirculation temperature sensor "A" circuit high, ut that may cause ive got a few its...

Holy ****.... where do I start.. lol

Has anyone got a ground location diagram (Think its a good way to start), I will also get the readings from the sensors & post

I have checked the wiring before, ut can't remember the values, so ill check them again.. With there pressure sensor unplugged, im getting 22 mpa (from memory) Thanks

I'm fairly confident with a multimeter... I've checked the 3 parts for the fuel sensors & they seem to be fine.. I'm just unsure where to check now. Thanks

OK, right, I was driving home and suddenly died... only fault code at the time was: P250A (Engine oil level - circuit) & P0195 (Oil temperature sensor circuit), after paying an auto electrician to plug it in, he told me at there was no fuel pressure (Showing 0 mpa in the rail).. I then ordered...

Delphi DS150e I have a mongoose, but can't get it to work.. so im stuck with the Delphi

Hi Guy's, im after some advice regarding the fault code: P0A94 on a 2011 Range rover Ive had a google and it only seems to e relevant to electric cars & obviously mine is a dirty diesel. I would e greatly appreciated if someone can advise me. Oh & the car turns over ut dosnt fire. Many...

I was thinking that if the sensor is unplugged, it should show either 0 or no data, so I was thinking that it could be a wiring fault, but ive had a good look at the wiring to find nothing at all.. how can I check to see if the injectors are firing? I feel at my whits end with it.. Thanks

Im after some further advise off anyone who can give it to me.. As said earlier, im getting around 17mpa, however, when I take the sensor off the rail, im still getting 17mpa (with no pressure), ad then when I unplug the sensor, live data is showing at 220mpa, has anyone known this before...

Hi, yes, read al the docs that you posted & yes, all lines seem to be clear Thanks & sorry for another thread, this is actually doing my head in now & just want it sorted

No, I was thinking that the rail would hold pressure until I cracked it, then it would loose pressure

Ok Guy's, so ive got a 4.4 TDV8 that won't start, turns over fine but just dosnt fire. I started off with live data showing 0mpa at the fuel rail, I've replaced the fuel monitoring valve on the back of the pump, the fuel rail pressure regulator on the left rail (as you look at the car) and...
