Disco 2 turns over, but doesn't start - Page 2

Sounds like the fuel pump. Sooner or later most of us have had to replace ours. Check out my site at www.eurotekapg.com for a good price, or call me and I'll see what we can do to get you back up and running.

wierd, sounds like my problem too, but without the hazards. My 97 Disco was running perfectly a few days ago, i may have ran out of gas and was on a downhill grade. Now after putting gas in it it just turns over and over without ever catching..
Im going to get a fuel pressure gage, and will listen for the fuel pump as well. i tried putting starter fluid in the fuel rail but it still wont start.. aNY IDEAS? Is there something special u have to do after the Discos run outa gas? I tried the fuel shutoff reset too.
THANKS

Then pull one spark plug-- re-attach the spark plug wire, and lay the plug on the exhaust manifold (threaded section of the plug contacting the manifold). Then with someone cranking the engine over --look at the spark plug tip for evidence of a spark. This won't work in sunlight, so hopefully your vehicle is in the garage.

Slightly easier is to use a spare/new plug and just pull the lead off a plug that is still in the engine - added benefit is you're not cranking with one cylinder at zero compression.

Not Sure if this Mater has been resolved yet!! I have a similar issue with my Disco 2 V8 here in the Uk, it will turn over just fine but won't fire. normally if i remove the fuel pump relay in the engine bay and refit it it will start. Although i my case there are no warning lights on the dashboard.

This sounds exactly like what happened with my '90 RR a long time ago and it was the inertia (aka fuel cutoff) switch.  This switch is supposed to cut power to the fuel pump in case of an accident and also, when triggered, activates the hazard lights automatically.  BTW, this automatic activation feature among many other features can be turned off with testbook or other diagnostic system like Rovacom. 
 
Check the 10 Amp fuse #13.  I believe page 88 in your owners manual has a diagram of the switch and its location under the hood.  It has a round top, is about 1-1/2 inches in diameter and 3 inches long, with a plug on the bottom.  It is attached in the engine bay to the main bulkhead directly in front of the right hand seat.  You push the diaphragm on top to reset the switch.  You may need to check voltage in and out.  If fuse #13 is good you should get current to the switch, and if the switch is closed (normal) you should get voltage out.  If this is in order, then it is probably the fuel pump itself, and you should climb under and poke your head up near the top of the gas tank, and with someone else turning the key 'on' but not 'start' you should hear a mechanical hum of the fuel pump running.  No noise=bad pump.
 
Hope this helps.
