Mr. Poolguy435,

The door lock operates a switch that signals the alarm and central locking system. The switch can be bad, and the cable from truck to door can be bad (very seldom - but will come and go as door is opened). You can pull out the plastic kick panel to left of driver's feet and expose a number of connectors. By using the circuits manual in the RAVE (free download below) you can find the two wires for the switch and meter them or short across them to simulate door key activity. It is a blue & green wire, and the switch shorts it to a black wire (frame ground) momentarily. You can poke a straight pin thru the insulation if you like to attach a jumper to, etc. RAVE has pix of the connector location, in gritty black and and white unlike the sophisticated D2 owners that have diagrams and pictures in living color.

 

95 Land Rover Discovery. Also not starting, but cranking. It was occasionally running, dying, running again for a short while, dying, but now not running at all. I was really convinced this was a crank sensor, so I bought one from ebay for a 95. Then we couldn't find a crank sensor on the car. I read another message that said that the 95s don't have cranks sensors... So what next? Spider? Immobilizer? or maybe the alarm/ remote locking system?

 

Have you checked for fuel pressure?

 

For me, it had turned out it was my crank sensor and I had just purchased a faulty one.
Car has been running just fine ever since! ☺
