Auto zone said the check engine light must be active to read the problem. Well, the 2002 discoveryII will go about 3 miles after starting (running great) then the engine light will come on at the same time the truck stalls and can not be restarted. Leave it set for an hour or so and it will start and run for another 3 miles before a repeat happens. What should I check? Help would sure be appreciated. thanks Mike

 

Check the basics: Battery connections, sensor connections - Cam, Crank, MAF. Look for loose or corroded Ground connections. What you describe sounds like a connection going open when it gets warm.

 

Thanks for the insight and advice.

Sounds like you have the typical crank sensor failure, pretty common, fairly cheap and easy to fix.

 

What he said, when the crank position sensor starts to fail this is "A" typical symptom, eventually the engine will not run at all.
Go back to AutoZone and buy a new crank sensor, then install it.

 

To the people who went the extra mile to give me insight into what my landrover problem could be- I say thank you over and over again. I will let you know what transpires after the fix is made. I will be trying the sensor solution first.

How to change Crankshaft position sensor 2000 DII - Land Rover Forums - Land Rover Enthusiast Forum

This is a write up on how to replace the crank sensor.

 

Like I keep saying, before you buy the part, test your old sensor to verify it is bad. Wait until it dies, then test it when it is supposedly not working. I hate to see people spend money on non-broken parts.

 

I had the same problem on a different car and it was the crank shaft position sensor.

 

I have a 04 disco ii same thing happened to mine. $60 for the crank sensor from autozone.
