What cause my 1999 land rover to turn over but wont start?
Sounds to me like the fuel pump. Located inside the fuel tank it can be difficult to verify without a second person or an extremely quiet workspace. First eliminate the basics. Verify that fuel is or isn't reaching the engine. Do this by locating the Schrader valve on the top of the engine. Battery side, aluminum tube on top of engine, the fuel injection pressure release valve looks exactly like air fill valve on your tire. Protect eyes, place a rag underneath the valve to catch any expelled fuel. With a small nail or valve tool press the needle to relaese pressure. If nothing shoots out or no more than a dribble is expelled, this is consistent with bad pump. Next check for the sound of pump running. This is where a second person come in. Have your helper sit in the drivers seat with the keys. Then move to the passenger side rear, fold up right side of rear seat exposing the carpet underneath. When in position, with all quiet, have helper turn key to second position doing so with driver door closed to eliminatebells and whistles. When the key arrives at position 2 this engages the fuel pump relay and fuel pump for 3-5 seconds. When the pump relay ceases to send power to pump after 3-5 seconds you will hhear one last beep from the message center. Repeat steps to confirm that pump is operating or not. You will hear the pump humming from the floorboards for the 3 second relay interval. If you hear nothing coming from the tank, which is directly under right rear passenger seat this would be the second confirmation of a failed pump. Assuming you have ample gas in the tank to prime pump (in the event it had run dry) five gallons, check your inertia cutoff switch for proper operaation and that it is not tripped. This switch is behind the right hand kick panel under glove box at right of front passengers feet. Remove panel and be. Sure that the red rubber switch is depressed. If this is pushed all the way down then the switch is engaged. Making this third confirmation symptom of bad pump.
The pump through the dealer is expensive, but if you are on a budget and have some mechanic skills, the $1500 pump can be repaired by simply replacing the $160 electric motor.
Feel free to repost additional info or questions. I will do my best to answer them. Good luck!
