Service Engine Soon came on this morning, took it to AutoZone to have the codes pulled. The codes were P1230 & P0455 but they couldn't tell me what they meant because Land Rover apparently wasn't in their system (figures). Fortunately, the truck still runs normally. Anybody had this before?

 

P0455 Evaporative Emission Control System Tank Detected (gross leak)
P1230
Fuel pump relay malfunction
Fuel pump relay open circuit - not the fuel pump

 

So the evap leak would be like...the fuel cap?
The fuel pump thing could be related to the fuel pump relay going bad. The truck died on the side of the road a couple of weeks ago and would just turn over and over and over and wouldn't start. So I thought it would be fuel pump related. Hit the relay under the hood with a screwdriver and it started. Drove to Advance and got a relay, was fine after that. Light came on over a week later. Related?
