I own a 1994 3.9 v8 landrover discovery,can you
'Check Engine' is a general warning light telling you there is a problem somewhere on the engine. **Note** It is supposed to come on when you turn the key as it is checking the engine electronics. It should go off after a couple of seconds to show the system is working properly. If it stays on get a good auto electrician to plug it into a specialist diagnostic computer to find out where the problem is.

If you don't have a 'code reader/re-setter', try taking the navigate battery cable off for about ten minuets and see if that doesn't clear it.
Why does it start on ether but will not run without it?
Because it is not getting any fuel! as soon as the ether burns up if no fuel then it quits. check all fuses and relay for fuel pump. to check fuel pump to see if its running. have someone turn the key to start, while somebody is under car at fuel tank. hold hand on tank, if it works you will feel the vibration from pump. most relays for fuel pump are in under hood fuse box. a fuel pump if good, will only run a few seconds to build up pressure in line. when engine starts it runs continuously. so you may have to turn key on a few times. Good-Day!
Water temp gauge sits 3 quarters or betweern halfway and hot when travelling dosnt get hotter or colder
Check or replace the sensor unit in the engine. If that does not solve the problem it could be the guage itself is faulty which might or might not be a easy fix. If it is like most new vehicles the gauges are on a PC board and not seperate which means replacing the whole pc board. If in fact it has sperate gauges you should be able then to just replace the guage if the sending unit does not fix the problem. Another thing to check is the engine thermostat it might be staying open allowing the engine to run cooler then it should.
