Omero Posted March 5, 2016 Share Posted March 5, 2016 Hi all, I have a 2000 defender td5 having the following problem. When its full, no problem what so ever, perfect starting cold and hot and runs like a breeze. But, whenever the fuel level is less than full it becomes difficult to get it started, and when its around 1/4 its almost impossible to start. Removed the fuel pump and and looked for any crack in the hoses, didn't find any. Any one familiar with such a problem or suggestions? Thanks, Omar Quote Link to comment Share on other sites More sharing options...
Dave W Posted March 5, 2016 Share Posted March 5, 2016 I'd suggest that the low pressure pump isn't working properly, when the tank is full it's aided by gravity but as the tank empties it's struggling to pump the fuel "up hill" to the fuel filter unit. You may well hear a different pump sound when it's full of fuel versus when it's low on fuel. The only solution is to change the pump unit if it is the pump.

Landrovernuts Posted March 6, 2016 Share Posted March 6, 2016 I have the same issue on a 110. I have a new pump ready to fit, but so far no time!! Quote Link to comment Share on other sites More sharing options...
Omero Posted March 6, 2016 Author Share Posted March 6, 2016 Thanks for your replies, Removed the tank and found a faulty non return valve in the middle of LP feed line, blocked it then started it for couple of minutes was ok. Tried to start again for a test drive and it was immobilized! Will start another thread fir that. Quote Link to comment Share on other sites More sharing options...
Landrovernuts Posted March 16, 2016 Share Posted March 16, 2016 Changed my pump last weekend and, touch wood, down to half a tank and no starting issues! Toby Quote Link to comment Share on other sites More sharing options...
