Landrover 90 problem

Hi I've got a 1988 90 with a 300 tdi fitted. I was driving it today and it ran fine for the first couple of miles but then seemed to run out of diesel so limped into the petrol station and stuck 20 quid in the problem I've got now is that it won't run anything above idle as it just bogs down and cuts out I replace the fuel filter but that didn't seem to sort it so I bypassed the lift pump and filter and ran the fuel pipe straight from the tank to the injector pump which sorted it for a couple of miles but now it's doing it again and I'm out of ideas can anyone help

It definitely sounds like fuel starvation. Have you blead the injector pipes ?

Ye every time in get it running I crack off the pipes at the injector but doesn't seem to sort the problem as it starts cutting out again near enough straight away

It could also be an air leak on the low pressure side of the injection pump

When you bypassed the lift pump, how did you supply the fuel?
As this might explain why it worked for a bit.

I joined the pipe going to the lift pump to the pipe which goes into the injector pump and then undid the injector pipe and cranked it over until it fired up but now I'm stumped as to why I've still got the problem

Hi just a thought it could be the pipe in the tank sh1t up, had that before, start there and work forward

More than likely a lift pump problem. Cheap and easy to replace, I'd start there if I was you.

To be honest I am not surprised you still have a problem as I said to someone on hear the other day. The lift pump supplies more fuel than is needed as it needs to presure feed the the system. Excess fuel goes back to the tank via the return line. If this blocks it normally will blow the injector leak offs, off. In your case though I agree with the previous comments, it is either the lift pump, or the fuel feed line blocked up.

So what to do... first remove the lift pump feed line and blow back down the line. You can do this with your mouth or an air line. If you use an air line keep the air presure low and remove the fuel filler (you dont want to blow your tank up). This should be free flowing within reason.
With the fuel feed line off connect an one end of another line to the lift pump, and feed the other in to a fuel can (at least 3/4 full as you dont want to suck air) connect a second hose to#the fuel return line, and feed this back to the same fuel can.
Then crack the fuel filter blead nipple / bolt until it can leak, manualy pump the pump with the leaver on the bottom, until the diesel flows air free.
Then tighten it carefully and do the same to the injection pump blead.
When this is done crank her over until you have blead all the air from the injector feeds.
Now she should run fine,when she has run for a bit 20 mins- 30 mins stop her and check the blead in the fuel filter. If there is any air you either have a leak or the lift pump is not efficient enough to keep up, and therefore you have your answer.


Let me know how you get on

new lift pump needed... under £15 last time I bought one and a quick fix


cheers steve

Was **** in the pipe work as ran the airline through all the pipes and connected them back up. It runs like a dream now

Pleased to hear that you are all sorted

Quite often it is the simple, most obvious things that get overlooked!
