Help.coming from the market, only rode about 500 meters when felt a judder, egine light came on and car lost all Power, pulled over let her rest a minute and tried again. As there was no missfire I tried again, it just got worse until it sounds like it's firing on only one cylinder. Got carted Home and used my iiD tool to clear falts, disconnected battery and gave it a charge. One fault I noted was electric thermostat wiring fault, checked connections, all seems OK. I suspected fuel, because it seemed to get worse but I have a quarter tank, could it be fuel pump? And how can I test it.I am running out of ideas any help would be much appreciated.

Pete (Haylands) is your man for this one, I am sure he will be along at some point if not PM him

Not sure how similar your symptoms are but these are the issues I had when my heated thermostat failed and shorted the wiring :

Read that post and checked fuses thinking " it can,t be this easy" well it was,t. Fuses are fine. Thanks for the sugestion it still sounds to me like a fuel problem.but then I come from a time when I used to reason that if you had fuel and spark then it should run not any more. Please continue the suggestions.

Don't big me up Ross, I haven't a clue, I can tell you the thermostat fault will have nothing at all to do with engine problems, mine has been disconnected for years and runs fine.... it's not a sensor so will have no effect on fuel delivery etc....

If you want guesses then

I'd check fuel pressure at the rail, there is a schrader valve to check it.... If low, could be pump...

If not camshaft or crankshaft sensor, also corrosion in the ABS pump socket can cause all sorts of faults....

If no helpful codes then it's good old fashion work through the systems, it needs air, petrol and a spark... you have to find what it's not getting....  Pete

Thanks Heylands, I like your thinking, I was just going through some posts on another forum dealing with checking pump relay and connections and of course if the pump is working. I am leaning toward fuel problems as when it first lost power it would run but rough and now it will crank smoothly but sound like it only wants to fire on one cylinder. Will start the journey of discovery tomorrow.

lots of the early petrol models, suffer from a fuel pump pressure failure. there is a valve to check pressure on the fuel rail, (silver pipe on inlet manifold. ) there is also, a fuel filter underneath, near to spare wheel well. if you have another inline fuel pump, from another vehicle, you could try plumbing it in underneath, and see if it fires up. theres a WIKI on how to change the fuel pump. i did mine, i only changed the actual pump at around £70. unlike others that bought the whole drop in assembly at about £400 -accessed under the rear folding seat carpet. when mine went, it just stopped, and would not fire, however it did start a couple of times, but cut out as soon as the pedal was touched.
easy start is one method, but you risk damaging the MAF. -if you over spray it. -you only need to know if it fires, -that you do indeed have a fuelling fault.
one easy way, might be to thump the petrol tank hard from the side, (underneth) in case the pump is stuck.
you guys down under, must have heard of this stuff..

Thanks for the encouragement, actually down Under we have what is called " Start you Bitch " I think it works the same.lol

All fixed checked fuel at the bleed valve on the motor, no fuel gotta be the fuel pump, lifted the carpet etc to access the pump, pulled the plug and checked for power, got power, reconnected pump plug and did the relay check, pump running, checked bleed valve and plenty fuel, turned the key and hey Presto she runs without a hitch, try a few more times and no problems. All back together and I can only guess that it must have been either the pump plug or the relay connections. I consider this to be a practice run for the next time
Thanks for the help :

If you need a new pump soon, which is probably likely, then get one from an X5 and just change the pump itself into the FF carrier, costs about a tenth of the price of a genuine FF one...  Pete

You are right Heylands it's probably due so I can order one in, at least it need not be a panic job and I can look for the best price for a replacement pump. It was most undignified for the ff to ride on the back of a breakdown truck.lol Cheers.

It's a Land Rover, it's use to getting a lift home.....  Pete

the plot thickens, went to fill up with fuel this morning, the guage read just over a quarter of a tank, took 99.01 litres so the simple fact was I ran out of petrol and must have formed a air lock, then with me playing around and the 3 litres or so that I added the air lock must have purged.I am bloody lucky I got to the petrol station so now for the first time in ages my fuel tank shows full.next project is to check fuel sensors. Any ideas??

Pretty well known issue I think, they just fail and need replacing, or fill it up at 1/3 full....  Pete

you could do no worse, for now...than to carry a red petrol can, with a spare gallon. in the boot. if lawful.
