What is your question?
It stays around three or 400 RPMs for the first 10 to 15 seconds after it starts only on a cold start. We replaced all three fuel pumps and fuel filters but still having the issue..., suggestions? Somebody suggested fuel relay. There are two fuel relays the one under the hood we have replaced but the rear one by the gas tank we have not tried yet.
What makes this problem better or worse?
Cold start only
How long has your 2012 Land Rover LR4 had this problem?

My goodness, why replace all these parts at great expense and effort without testing? Testing would not have condemned the pumps because you didn't fix anything. Stop with the fuel delivery guesses. Consider that engine performance needs: Fuel delivery Ignition Spark Air to the intake (or no air) Exhaust flow Emissions controls Engine timing Engine compression Not sure why you're laser focused on fuel. Testing is needed. I'd guess emissions control or air intake concern. But check it!
