    Hi fatladclyde, I want to help you with your question. Are there any other warning lights? Does the engine wind when you turn the key or nothing at all? Can you please add details in the comment box.

Note the OBD CODE under the seat and interpret the code on the following website.
Land Rover On Board Diagnostics Codes Pangaea Expeditions

Land Rovers were equipped with an LED readout as part of their OBD (On Board Diagnostics). Unfortunately, all this LED gives you is a two digit code, which is equally meaningless unless you know what that code corresponds to. The exact location of the LED reader varies based upon vehicle model and model year. Generally, it should be found near the ECU for the vehicle. On the 1994-95 Discovery the LED readout is under the passenger side seat,

'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.

SOURCE: Fuel supply problem in 1998 Landrover Discovery. 3.9 V8

not likely a fuel issue,
try running it in the dark of night , no lighting and look for sparks ,
have the ignition coil tested , be sure it has good ground.
pull each plug and watch the spark ,does it maintain the blue long arc.
tune a am/fm radio to the sparks ignition sound an listen to it
a portable walkman can lead you to the faulty spark,
or just have them monitor the spark at the shop.

SOURCE: Landrover discovery wont start but battery is good

This usually is the starter, especially if your truck has had an oil leak going for a while as the oil will run down into the starter and cause it to intermittenly fail. Also check your battery terminals and make sure you have a good connectivity.

SOURCE: I have a Landrover Discovery 2 V8 2001 model and

you may have bent one of the wheel sensors and is causeing the traction control to come on, and for the brake light is it amber or red? if it is red does the brakes feel spongy? if it does you have a mechanicl malfunction on the brake system. so the first thing to do is checks shoes and brake fluid level, als o be sure E brake is not slightly engaged, if you bleed the system this may fix the brake light problem but the whell sensor could be causing most of your problems causing it to brake going down hill, if the auto adjuster is not working this could casue it also, however be sure the brakes feels solid, take it out on a road with no traffic get it up to 20 miles an hour and slam on the brakes and come to a stop, put it in park and go outside and lok to see if the wheels all locked up and dragged at the same time if they did you are most likey ok, if one wheel did not lock up at the same time that will be the wheel you have a problem with, you will have to remove the drum or rotor if it's rear disk brakes to see what is causing the problem. Therse are the most common problems you will find and if you don't spot the trouble then you would have to jack the car up with all four wheels off the ground and have someoen push the pedal on the brakes in while you slowly turn one wheel at a time notice when the wheel stops anddo this to all four wheels. if you find one wheel not stopping then you have a mechanical problem with that wheel, it could be a bad adjuster or frozen adjuster or worn brakes or even a crakd drum ow a wheel cylinder froze up. Doing this will save you time if you have to take it to a shop as you will have isolated the problem. if lets say the rear wheels do not stop with the pedal all the way down it means you have a bad master cylinder. hope this helps and thanks for using fix-ya.

Hello i have a landrover discovery the im obilizer of the alarm is on how do i get the car started? car wont start

Thanks for choosing FixYa and welcome. You will need the code to start the vehicle now. Check your owner manual to see if it has the code. If you can't find it online or in the manual, you can call the dealership to get the code. It will cost money though I am sure of. Be careful online also. At least with the dealership, you will get the correct code. The code will be the only way to get it starter though.

ENGINE CHECK WARNING LIGHT ON

Before you can even attempt to correct what's wrong with the car you're going to need to obtain the trouble codes associated with the light. If you do not have access to an OBDII scanner you can take the car to most any parts store and they will check the codes for free. Then post them here and we can guide you.
