im going to check my fuel system today and see

 

alright, is it possible to rebuild the pump in the disco? i don't want to have to buy an expensive pump.

 

[QUOTE=No Doubt;660766]You know that you have low fuel pressure since it starts with starter fluid but not without. Could be the fuel pump relay or even a corroded relay or fuse box, but is most likely a dying fuel pump (easy to replace under your back hatch carpet).[/QUOTE
so im guessing that the engine is sucking its own fuel into the motor in higher rpms? then once it gets to idle it cant pull enough fuel for its self to run off of? or is the pump weak and cant pump enough? it will run as long as i want, just as long as it doesnt drop under 1000ish rpm

 

" i don't want to have to buy an expensive pump."

I know its a bad time for this reminder, but you bought the wrong car for that kind of attitude. Owning a Land Rover one should know going in that proper maintenance is not an option but a requirement. The only way to cut the cost is to do the labor yourself. AB has them on a Flash Sale right now.

 

There are tons of options depending on your skill level, comfort level, and pocketbook.

The Bosch replacement pump is just $136 at RockAuto: https://www.rockauto.com/en/catalog/land+rover,2000,discovery,4.0l+v8,1363496,fuel+&+a ir,fuel+pump+&+housing+assembly,10147

The actual Land Rover fuel pump from Atlantic British is $224 during their current flash sale.

Some people use a generic inline fuel pump, which can be as cheap as $35 but requires doing your own electrical and fuel line plumbing.

Others buy a used fuel pump. I picked one up on eBay for less than $40, and local wrecking yards sell them even cheaper.



...but... before doing that, let's first *TEST* your Disco 2 to see our problem. Heck, a bad alternator/battery (failed internal cell) can reduce fuel pressure. So start her up with starting fluid and rev her a bit to keep her going and then... Turn On Your Headlights, foglights, radio, and step on your brake pedal.

If your problem is marginal voltage to your fuel pump, then the above might identify a problem other than, or in addition to, a tired fuel pump.

Test first!

 

 

 

yes im an ASE student, i know how to do it, just i dont want to dump more money into something i dont know will work.

 

First ensure the autobox gearshift is in P or N. Switch the ignition key to 2 then open the rear door and if the pump isn't whirring it is dead and there are no serviceable parts so it will only take the cost of a new pump plus the rubber gasket. The D2 will only start in P or N.

To change the fuel pump is a simple 2 hour max job, see here:

www.discovery2.co.uk / TD5 Fuel Pump replacement.

You don't need to remove the rear side panels for access as the carpet usually slides out underneath the panels. The V8 pump is normally the same or similar type to the TD5 but with less connections into it but it's in the same location.

 

replaced the relay (number #1 in the engine bay fuse box) and i turned the key half way to let the fuel pump kick on, at the same time i unplugged and plugged my MAF, and it started right up. WITH NO SES LIGHT EITHER!, thank you everybody for your help ill keep updated if something happens again!
