Hi Jackie,

I picked up my truck last Thursday and crossing fingers they actually found and fixed the issue this time! This is what they wrote on my paperwork;

"removed ecm to check for signal from fuel pump control module, at connector C0635L, and found signal grounded at times, intermittently, removed rear luggage compartment trim to check for fuel pump control module, to check for signal grounding, indeed was grounded. follow the wire under the rear seat, had to remove seat and trim to chase wire, wiggle wire with the meter hooked up, found peel wire close to the fuel pump control module touching ground when wiggled the wire loom, go for an extended test drive and working as designed"

So far, I've driven the truck a few times and there have been no issues....yet! The deanship stated that my eco start/stop which was not working correctly should also now be working however, it still doesn't. It works intermittently so I will be taking it back in for that however, I wanted to drive the truck around town for the week to make sure it doesn't stall out again so I don't have to keep going back and forth.

Have him chase the fuel pump wires since that has been replaced. The dealership stated that my fuel pump had been replaced at about 4k miles and that more than likely this is when the wire became loose and overtime it probably moved around and then started causing the engine stall.

I will post again in about a week with an update. Good luck!

Hi Jackie!
So it seems that my LR4 is back to the same old thing. The last fix regarding the wiring did not fix the issue and my truck staled out/shut off 2 more times! It's in the shop for the third time now. This time, my engine light came on and stayed on which has never happened in the past and my truck wouldn't start back up for several minutes after it happened this time. We'll see what they have to say this time however, my understanding is that it can really be just about anything that could cause this to happen. The fact that the service department keeps telling me they fixed the issue, only for me to keep experiencing the same problem tells me that they don't know what's causing it either.
Any word on yours yet?

 

Were you able to find the fix this issue? Mine is doing the same thing.

 

hi
Did you have fix your?I have same problem with my lr4.Thanks

 

no, I haven't been able to fix it. I'm exhausted! My mechanic is exhausted. We thought that it might have to do with something getting wet too, but it doesn't seem to matter. Wet or Dry it keeps dying. Random times! I can go days, not a week, without it dying. And then out of the blue it dies. I don't trust it. I drive it around my small town, because if it dies, I usually can get it started after a few seconds/minutes, and its low stress, no busy streets. But we took a little road trip and I wouldn't take it. I ended up renting a car, ridiculous. The mechanic has checked batteries, fuel pumps, computers, wiring, I have a laundry list of items we have replaces. No codes, just dies.

 

I was finally able to fix it !! It took me three day's to figured it out,$20 bucks repair. Randomly dies while idle, sometimes during drive dies for fraction of second and starts itself,really scary experience .No codes...then u0100 code ..lost communication with ECM/PCM.I checked all wiring, batterie fuse's ,relay's.all seems to be good so I switch 70 amps ECM relay with another but only 40 amps relay and its start to dies more often and finally throw the code that relay is re-energizing,not able hold contacts.So I bought new 70 amps relay for ECM and problem solved! that was my first guess it could be a relay,but I did measure resistance ,checked contacts,all seems to be good,but relay was tired and after while wasn't able hold contacts and that cause the problem.Yours could be different story,but you should give a try even if the relay seems to be good!

 

I showed my mechanic your message, he worked on it and it hasn't died since! I didn't want to give an update right away and jinx it, LOL! But its been just over two months and I haven't had a problem. Thank you so much for saying something, you really helped me out. I was at my whits end and was looking at trading it in, which I didn't want to pass the problem onto someone else. Thanks again.

 

I have a new issue with my LR4, could you look at my recent post and see if you can help me with my new problem?

 

I've had the same problem with my 14 LR4..just dies going down the road or idling..replaced crank sensor, cam sensor, and about to attempt to clean the return line fuel condenser/filter..any help appreciated..also what is your new problem as I can't find the thread
