Disco 2 - no start

**ozscott** · 5th March 2016, 02:08 PM

Hi guys,

The joy of long term LR ownership continues.

Disco 2 manual trans. Running well except for intermittent rough idle and a bit low on power. Stalled one day when reversing into a car park - at revs it would not normally stall at. Then hard re-start - took 10 seconds of spinning to start. Then ran fine.

Replace MAF with genuine. No change except for a little increase in overall power but still a bit down and still intermittment rough idle. No starting problems.

Day of MAF replacement occasional rough idle and went to back into a car park. Same stall and then no re-start at all.

Does not seem to have spark. I cannot hear the fuel pump unless shorting the under bonnet pump relay...with pump running while shorting it still will not fire.

It had a new crank angle sensor (genuine bosch) about 8,000k ago but I am thinking it could be that (does a failed crank sensor cause fuel pump to remain off as well as no spark???)....

Could it be the underbonnet or underdash fuse box (have checked all fuses in both)?? OR at a last guess ECU?

Grateful for any suggestions

Cheers

CAS?

I think it might well be Evo. Justin posted up a while ago - I just read his post where the fuel pump will not work AND no spark when CAS goes out to lunch...seems odd that a new genuine one would so so within 10,000k but I suppose if they are going to fail then they might fail quickly. I will have to put my old known good one (260,000k...) in and see what happens. Can you do the swap without removing manifolding? Also what is the easiest way to unplug?

Cheers

So...weather cover held on by one bolt and cover is loose...what's the bet water from the water crossings i did 2 months ago had got in there (or oil...!!)

**Pedro_The_Swift** · 6th March 2016, 05:27 PM

there is a bit of oil around--

may I ask where from?

and I would NOT have expected a new one to fail so soon,, or ever, really.

Pedro its a Land Rover.

Ive seen them do 200k+ even soaked in oil and coolant leaks...😮 still it does sound like CAS to me....

mines just about dripless after the last million I threw at it,,

I have a small (5 year old now) seep from the ACE pump which the visc fan tends to move around a bit,, but its just not worth fixing

Million dollars?

Thanks Justin. I think so too. I have read RAVE on them and sudden stall and also no restart is typical. I might have just got a dud.

Of course RAVE did not contemplate fuse box PCB failures and I suppose it could be that. My parts guy says he sells every box he gets from wrecks...

Cheers

Would the CAS cause the rough idle and loss of power? Maybe two things going on; MAF and CAS?
