Have a 2005 LR3 -original owner. Replaced battery (Interstate MTP-H8) December of 2011. Moved from CT to FL in early 2014. Battery is showing signs of failure. Trickle charged overnight and still won't crank the car. I replaced failed alternator in the fall of 2013 with OEM part. Is it possible that the battery is really dead after only 4 years? Is FL heat likely a factor in that?
When working with GEMS vehicles. Never try to locate a misfire by pulling plug leads off - pull the injector connector instead. Otherwise you can blow up the ECU.
Secondly never swap ECUs between vehicles to test them, because both vehicles and ECUs may stop working, and you'll have to have them all reset by a franchised LR dealer (ouch!).
