hi

there quite a complicated setup on the R's

2 fuel pumps, one comes straight on the other runs to top up the fuel pressure on higher boost which is controlled by a module

I'd check the accident fuel trip button and fuses, then possibly the fuel pressure sensor on the fuel rail

its a returnless system, no regulator, no return fuel line, work off a pressue sensor and control the pumps

ideally you want jaguar ids/sdd plugged in and see what faults there are

cheers

pumps work with direct power to them, 2nd hand module bought from eurojags , no joy, all fuses checked a couple 10amp  had blown ie..dash illumination etc 

 

checked and double checked everything you mentioned Joe  even checked all pug ends for voltage etc   nothing!! 

but put direct power to the pumps and fires straight up???

ps.. yes there is fuel in😆

HI

looks like the fuel pump relays not pulling in

its controlled from rear body module, the replacement fuel pump module may need programing to the car

only way really is to get jaguar IDS plugged, see what you have, also I think you can test run the pumps though the software aswell

only other thing, may be work rechecking any connectors you have unplugged, look in the plug, some times the connection/terminal comes loose and is pushed into the plug, so theres no connection

theres no after market imobiliser on it, that may be playing up

cheers

ok update time !!

problem solved..turned out to be a bad connection on the master plug (on the fuel tank) plus battery being a bit weak.

so all fixed and off for an mot .....which it now failed on 1 tyre having a cut on the inside (missed this I admit) and the lights being "too low on the aim" due to the self levelling not working 😖😖

any ideas on why they have stopped and any remedies accepted

hi

headlights stop leveling if you has a faulty front or rear level sensor

if the headlights are unplugged with the battery connected

or it could be broken adjusters which is very common, improoved ones are available on ebay and are not a massive job to do

also the faults above can only be reset with jaguar ids/sdd to get them working again

cheers

so basically it needs jaguar to program them if we can fix them before going for mot again Joe? 

has it happened  because of the battery being disconnected?? just seems to have happened!   

all new to me so do appreciate the help  thanks

hi

its hard to say why its happened with out reading codes off the headlight leveling module

but if the battery was low that could also cause it, maybe nothing wrong but low voltage fault, because it does the go all the way up, then all the way down, then levels the headlight beam, every time you switch the ignition on

only way to reset is with jaguar software, if theres a local jaguar indy near you might be getting them plug in and see what fault code is, should'nt cost too much as its a 10 min job tops

cheers

2 new front tyres and sorted headlights = mot pass with no advisories 👍👍🤩
