SupporterMy 2001 HSE 4.6 died mid flight on the way home from work this arvo. Right on a very busy roundabout at peak time too
First thing I did was check all connections, hoses, etc, but found nothing obvious.
Called RACV for a tow, a very nice Disco ownwer came to the rescue and towed me out of the way of all the traffic, thanks Anthony!
I'm not sure where to start with this one, I could not see any spark, but also could not hear the fuel pump working. It is turning over fine, no errors on the dash, faultmate had no faults showing. Was not overheating, actually has been running really well for ages. I had no warning at all, it just died. My first thought is crank position sensor or fuel pump. I've never had to test either of these before, can anyone point me in the right direction?
Any other suggestions?
Cheers, Pete.

Use the garden hose to dribble cold water onto the area around the crank sensor. If the engine starts when the CKPS is "cold" then most likely that's the problem... the permanent magnet in the nose of the sensor eventually becomes too weak (because of heat and vibration... ) to register a pulse. If it does start, it will probably stop shortly thereafter when the engine warms up and the magnet "dies"...

Hoges nailed it!
Perfect weather and year for crank position sensors to die.
Are you at or around 200,000 to 230,000km on the odometer?

Well done Hoges, the knowledge here is scary. Maybe there should be a green stamp award once a month for the best advice
By all means get a Defender. If you get a good one, you'll be happy. If you get a bad one, you'll become a philosopher.

SupporterKeithy do you have a hidden camera in my car? It is indeed about 230,000km!

That's the magic odometer reading for crank sensors to die! Very few die earlier, none last longer!

I've just replaced mine at 350000km. As far as I can tell, it hasn't failed but I'm chasing a very intermittent (can go 6+ months without appearing) non-fire when cold problem.Originally Posted by Keithy P38

If it's done that many k's and hasn't been replaced by a previous owner, then you've set a record! Some decent k's you've done there!

SubscriberThanks for the compliment! HOWEVER... this issue has been explained a fair bit on these pages recently... guess that with SWMBO regularly interstate these days, tag-teaming with her sister to care for their invalid nonagenarian mum, I get a bit more time to imbibe the detailed knowledge in this forum... that's the problem with any thought of switching to a different model... have to learn all the little quirks all over...Well done Hoges, the knowledge here is scary.

The dealership I worked at did all the work on the car from day dot. There's no mention of a crank sensor in the history. Fuel pumps on the other hand....
