Cough. Splutter. B*ll*cks.

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, Erik-Jan.

No. Not at all. Ever!

OK

Oh joy...

David

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.

I'd assumed mine was too early, but have to say I haven't checked (and I'm not with car right now).

Anyone know when access panel was introduced?

David

Blocked fuel tank breather?

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

David

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.

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...

beamendsltd uttered summat worrerz funny about:

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.

Bah.. Austin, you teased me!

David

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!!!)
