I was traveling about 50MPH and without warning the engine lost power and shut off. Got an error code about fuel pressure.
Jumped the relay and fuel pump did not come on. Replaced fuel pump and still will not start, just turn over rapidly.
Tried starter fluid to see if it would crank but did nothing.
Engine is the V6 2015 LR4
any ideas?

 

without codes??

 

look, you really need to start following the pinpoint tests in the workshop manual.
Otherwise you are ineffectively hunting and pecking and playing the musical parts game… inefficient, wasteful…
For example, relays are managed by modules…. your approach was inadequate as it does not test for the root cause.
Furthermore, starter fluid?? Really?? its not the 1970’’s any more, and that is not a carburator and that is a fuel injected engine.

Trying to help but we need to de better than this.

 

LR4 2015 going down the road and suddenly lost power and shut down.

Got the following codes
P0528-00 Fan speed sensor circuit no signal
P0483-36 Fan performance
P0327-11 Knock sensor 1 - circuit low input bank 1
P0327-00 Knock sensor 1 - circuit low input bank 1
P0332-00 Knock sensor 2 circuit low input (bank 2)
P008A-82 Low pressure fuel system - pressure too low
P0144-00 Oxygen sensor - circuit high voltage bank 1 - sensor 3
P0147-00 Oxygen sensor heater circuit malfunction bank 1 - sensor 3
P0055-00 Heated oxygen sensor heater resistance (Bank 1- sensor 3)
PooBC-00 Mass or volume air flow A circuit range/performance - air flow too low
P0328-22 Knock sensor 1 - Circuit high input (Bank 1)
P0333-22 Knock sensor 2 - Circuit high input (Bank 2)
P0008B-07 Low pressure fuel system - pressure is to high
P007C-00 Charge air cooler temperature sensor - Circuit low Bank 1
P0420-00 Catalyst systen efficiency below threshold Bank 1

Any thoughts? I have not tried to clear codes and see if that does anything.
How do you check the fuel pressure? i don't see a port to check that

 

How many miles on your vehicle? If I didn’t know better I wonder if this is a clogged cats issue.
Is your maintenance up to snuff? It also seems your air filter is clogged.

 

the odometer showed 160k. When I hooked up to scanner it showed 260k
have had almost 1 year and have had serviced.
just got new air filters as i do not know when they were changed

what is a “clogged cats”?

 

I had not experienced any acceleration or other issues until the vehicle just suddenly stopped

 

That is one crazy set of codes. I’d have mine at the shop already.
260k, Look at the owners manual for what need be completed in the maintenance schedule…

ECM error? or the catalytic converters are plugged (thus not allowing exhaust gases to exit properly) is my guess from afar.
Like I said, I’d be at the shop already… this could be a big one… I say that as there are no CAN bus communication error messages so, everything is talking.

 

I am 2+ hours from Land Rover dealer would have to take it on roll off at this point.
The check engine light never came on until this happened

 

As you’re off warranty a well versed in LR inde (with subscribed access to topix and all the catalogues) might be the better choice… but
Even off warranty, I have called 1-800-461-2325 for LR assistance and they did send a flat bed, they did take it to the dealer, and get this: I wasn’t charged for the service.

Jag has done the same for me in the past…
