Starting, with air in system

2.5DT 1997 RR, so there i am under the bonnet looking at the fuel pipe from the filter to the injector pump and i ask her who must be obeyed to simply turn on the ignition (car is cold) and what do i see, air bubbles by the plenty being pushed forward from the filter end towards the pump, i tell her to turn it off, then back on again and a few more air bubbles and hey presto car fires up first time.

When hot i assume the pump in the tank pushing fuel forward which is activated by the engine temp sensor and glow plug relay does not coe into play?

Any idea's where the air is coming in, where to look first with any common leaks to look for?

Thanks
Alan

Change all the little braided rubber leak off hoses on the injectors and the one from number 1 injector back to the injector pump. Think you will find it will be ok then

2.5 deisels have a long standing issue with this causing prolonged cranking once car has been stood for several hours this it can be 1 of a few things

it could be the leak off pipes as previusly suggested;(these normally apear damp if these are at fault)if air can get in deisel can get out.

in my experience this issue has been the fuel pump in the tank, the one way valve fails causing air to enter from the tank, you will need a new pump if this is the case ESR1111, tank has to be removed or this

best to check the seals on the in and out ports of the fuel filter housing though this could also be a cause,

Land Rover have fitted a brand new fuel pump in the tank just a week ago and no cure, i will get the leak off pipes changed and see what happens. Thanks Alan

Simple things FIRST !

I now have the same problem! has it been resolved??

Change the o ring filters at either side of fuel pump first. then change all plastic and rubber fuel pipes( including clear ones).
if that does not work unplug engine coolant sensor from below no 4 injector ( its well hidden but a long screw driver will assist in unhitching it from the sensor).

Unfortunately landy dealers have a lader diagram that theye use to solve this problem and after they change the fuel lifter pump and fuel pipes they have not got a clue so they will try and change all the expensive bits for you.

In my experience it is 90% always the coolant sensor that is giving an inacurate reading.

Thanks for your quick reply, I have remembered, the strange thing is, this fault only accurse when the fuel tank isn’t full, as soon as you fill it over say 1/2 way, it starts as sweet as a nut! So something going on there

I’ve ordered a pump from Island 4x4 cheapest i could find, for £98 + P&P £5 01795 580332 hope this sorts it out, its only a 3/4 of an hour job, if i get it the w/end should be sorted thanks for your help, if it works i will tell you all

sorry i will start a new thread i think!!
