Car Forum / Land Rover Cars / November 2005Cough. Splutter. B*ll*cks.
Rangie semi-died last night. A mile down the road after brimming the tank, suddenly losy all power. Would sit and idle perfectly (smooth, no missing) and would start normally, but would just not rev at all, and absolutely no power. I managed to limp her home, but any sniff of throttle would have her coughing and backfiring, as soon as I lifted of, she would idle normally again. As yet, I haven't even lifted the lid, but first thoughts are fuel pump. Comments? Anyone got a cheap fuel pump I can swap in to start chasing problem down? Toying with the idea of removing the floor to access tank from above (see here) http://www.rangerovers.net/repairdetails/fuelpump.htm Probably fraught with hidden dangers so would be grateful if someone could talk me out of it. David 1986 EFI Range Rover Sounds familiar. Will it rev eventually? Mine turned out to be the fuel pressure regulator at the back of the EFI chamber. Found this after changing about everything else!!! Martin > Rangie semi-died last night. > [quoted text clipped - 22 lines] > David > 1986 EFI Range Rover >Sounds familiar. >Will it rev eventually?

I think just coincidence, but thought had occurred that maybe bad fuel. However, starts normally, idles normally. Can't see a v8 idling on a tankful of diesel. Thanks for thoughts.

We had to replace the fuel pump on our 1990 Discovery several years ago now. I think the access is similar to that of the Range Rover. It would start, but as soon as you tried to move the car was it really struggled. On another occassion we've had a problem with a blocked fuel filter, which was replaced and car ran fine. Nikki > We had to replace the fuel pump on our 1990 Discovery several years ago > now. [quoted text clipped - 3 lines] > was > replaced and car ran fine. Similar symptoms on my petrol 90, 30mph max, ask anything more and it died but after a couple of mins sitting it would start and run as before. Obviously fuel starvation. Thought it was the fuel filter but wasn't, eventually turned out to be a dodgy fuel pump not delivering enough to the carb (which had already been changed but wasn't the problem, expensive mistake!!!)

Lee D Signaturewww.lrproject.com Not sure what the rangey has, but in cars with points ignition, if the gap is too small, the car will idle perfectly, but will not like revving as there is not enough time for the charge to build-up in the coil. but as it's EFI, i assume its got electronic ignition and all those gizmos. Just a thought. Sam. I had a similar problem with my 87 rangie and it turned out to be a lead , it would idle fine but when you tried to accelerate it would misfire, pop and chug along. Got the leads sorted and it was fine, hope yours isn't to drastic Bren > Rangie semi-died last night. > [quoted text clipped - 22 lines] > David > 1986 EFI Range Rover > As yet, I haven't even lifted the lid, but first thoughts are fuel > pump. > > Comments?

Like this option (cheapest new pump I've found is £100ish, and thats Paddocks, been quoted over twice that elsewhere...).) >Disconnect the fuel feed pipe, post filter, and stick it in a clean >container and switch on (don't crank!) fuel should gush out... Should pump activate as soon as ignition is switched on? I THINK i've had a fiddle with a Disco pump before, that only seemed to get a feed when the engine was cranked. Could be wrong of course. Ta David > Should pump activate as soon as ignition is switched on? I THINK i've > had a fiddle with a Disco pump before, that only seemed to get a feed > when the engine was cranked. Could be wrong of course. If I remember correctly, fuel pump activates when the flap of the air flow meter moves. You should hear it starting by removing the air filter hose from the AFM. Turn ignition on and push the flap seen in the opening gently with your finger or a screwdriver and listen. Measure the fuel pressure first before changing the pump and/or the regulator into new ones. You might end up saving some money. It should be around 2.5 to 3 bars.

I THINK i've >> had a fiddle with a Disco pump before, that only seemed to get a feed [quoted text clipped - 6 lines] > Only the EFi ones need the starter engaged, I think. Is this one still > on carbs? I've now done what I should have been done before - it's an EFi! Avoid jumping to the obvious conclusion that the full tank is the cause and/or that it's the pump. Check the easier to get at bits first: it's more likely to be an electrical gremlin. > Should pump activate as soon as ignition is switched on? Well every car that I've owned does, you can hear it whirr away for a few seconds. Of course Land Rovers being Land Rovers... I am talking about the tank/delivery pump to get the fuel to the engine not the high pressure injection pump. The latter I would not expect to do anything without cranking.

Derek > Rangie semi-died last night. > [quoted text clipped - 22 lines] > David > 1986 EFI Range Rover Hmm - EFI's have a short-ish rubbery air hose thing between the air filter and the plenum don't they? Maybe it's gone soft and when you're idling and there's next to no suck it's fine, but as soon as you put your hoof down it sucks together and chokes it up. At cheap and simple first look you must, said Yoda. Steve >Rangie semi-died last night. AAAAARGH Went to start diagnosing last night, armed with borrowed fuel pressure test kit. Start Rangie up to move her into the shed. Perfect. Starts, idles, revs. Perfect. take her for a 20 mile run, including blasting up and down the motorway. Perfect. As I see it 3 options. 1) Start wasting time ond money trying to diagnose whatever the original fault was. 2) Worry that the next time the fault occurrs will be somewhere wet cold dark and inhospitable. 3) Assume that the fault was magically cured overnight by the fix-it faires. Being a "glass is half full" kind of guy, I'm going with option 3. Ive liberally applied liquid maintenance (WD40) to everthing mentioned in the thread to ward off further evil spirits. However if you do ever see a gently dilapidated D plate white Rangie crawling home at 6 mph, "I told you so" will not be appreciated! Many thanks for all the advice and any further thoughts most welcome. David >Being a "glass is half full" kind of guy, I'm like that - life's too short.
