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.

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!!!

Coincidence...or just the wrong fuel?
Petrol instead of diesel or so ?
Kind regards,

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.

you ought to have an access panel in the floor...

I had a go-slow fuel pump on the disco. it was still running, but not
delivering enough fuel.

bought one off eBay, ISTR.

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.

Anyone know when access panel was introduced?

Blocked fuel tank breather?

If Your specification is vague or imprecise, you'll likely get what you
asked for not what you wanted!

He who says it cannot be done would be wise not to interrupt her doing
it.

First thing I though of too, but symptoms same with fuel filler open.

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

Cruddy new fuel or a very empty tank that has the sludge stirred up
and sucked into the fuel filter causing starvation?

Disconnect the fuel feed pipe, post filter, and stick it in a clean
container and switch on (don't crank!) fuel should gush out...

Worth checking the "+" and "-" wires to the coil are firm. My 1983 Rangie
gave similar symptoms due to a loose wire now and then. OK when you knew
what it was.

Like this option (cheapest new pump I've found is £100ish, and thats
Paddocks, been quoted over twice that elsewhere...).)

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.

Yep, you should also check the ground wire of the ECU. I had similar
problems just lately - fixed it by stripping the wire and making a new joint
to the side wing.

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.

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!!!)
