Hi Guys
I need your help. I own a 2011 RRS and for the last year I am trying to fix up the issue with the car. I live in Virgin Island so I am limited to a professional Range Rover service.
My car won't start sometimes It will crank but won`t start. This happens on occasions. I can drive the car with no issues for few days and out of the blue it will not start or the engine will stop during the drive. No dashboard warning light I have scanned the computer and no error either. I have already replaced:
1. Fuel pump
2. Fuel module
3. Cam shaft sensor
4. Fuel relay
5. Fuel pressure sensor
6. Crank position sensor
If you have any other ideas what could be the issue please help I am desperate. I love my car and I want to keep if for few more years.

Thanks

 

What codes are you getting?

 

Hi

At the begging the only thing that the computer was able to detect was the fuel pump assembly. I have purchased of market brand. It helped for a while but then again back to my issue. I have now purchased an original Land Rover fuel pump assembly (waiting for it to arrive) as i have heard that this might be the problem. Do you know if there is any adjustment to the new pump after installation or everything should work fine by just putting it in.

Thank you for your feedback!!!!!!!!!!!!!

 

No adjustments that I'm aware of on the pump. The fuel pumps in the motor are timed to the motor, and that's how it controls pressure.

Have you given the throttle body a good scrubbing and cleaned the sensor on top of it?

My dad's was getting weird acceleration, not starting a few times, and going in limp mode. He had codes all over the place. After cleaning the mafs , throttle body, and that sensor, the issue disappeared.

I have an XFR with the same motor, and they have a faulty fuel pump problem recall.

Check to see if Range Rover has the same problem.

 

Thank very much for this information I will pass it on to the mechanic. Hope this helps

Hi Shadow993

So i have purchased an original fuel pump and original cover and new harness for it also new fuel relay.
And it didn't help. Car is still shutting of from time to time. The mechanics here are not familiar with this issue so Im just throwing money out the window here. If you have any other suggestions what my cause this please let me know. Some people are saying i need to change my spark plugs, wires and clean crankshaft position sensor. ( i got new sensor installed so its not it.) Few people say to change my coil as it might be clogged.
I also got new fuel module installed all part are original LAND ROVER.

 

What codes?

Have you cleaned the heck out of your throttle body and the sensor on top of it?

In the past stalling was caused by carbon/dirt/ oil build up on the throttle body. I veli be there is a pin size hole in the bottom that gets clogged. If it's like the one on my jag XFR

Clean that and your mass airflow sensors with the proper cleaner

 

No codes. I will tell them to clean the throttle body but i think they already did it in the past. I will address the mass airflow sensors as that might be the issue.
I have read the the fuel injectors might be faulty but i would loose power if one of them was not working right?

 

Right... if it was a coil or injector , you would definitely get a code.

A misfire code or a lean code.

Hook up a Bluetooth code reader... then you can watch it live. So when it starts giving you trouble their might be a pending code.

I had a misfire that wouldn't throw the CEL, but showed as pending on occasion.
