I Don't Believe It!
 

Car failed to start yesterday afternoon. First proper fail to proceed
in 8 years. Not too shabby.

However, I suspect the immobiliser is playing up. It cranked fine (for
as long as I could be bothered holding the key!) and I could hear the
fuel lift pump so I'm suspecting the immobiliser is playing up :-((

AA man arrived in good time and, after setting off the alarm by
entering the car using just the key (who still does that these days?!)
the car fired up like a good un!! My neighbours face, who heard me
turning it over for substantial periods, was a picture - you could
hear his jaw drop. AA man was well pleased at an easy fix and time for
a chat!

Car's been ok since. Anyone any experience of this sort of thing?

Also, how the hell does the emergency start procedure *work*? It says
in my book turn the key to MAR, press accelerator fully then wait for
the engine warning lamp to flash - er no it didn't. Fell at the first
hurdle..any ideas..anyone?!

That sounds possible. Let's hope it's something as daft as
that......instead of something more sinister.

Mine does that pretty regularly.

Correct. Took me bloody ages to work out what was happening.

How does the immobiliser work? Sounds a bit daft to allow cranking and
fuel injection.

None at all.

The lift pump is in the fuel tank and feeds the high pressure pump in
the engine bay. There's a return feed to the fuel tank so the fuel
that's not squirted through the injectors circulates back to the tank.
Common rail diesel injection is, in many respects, very similar to
petrol injection fuel systems except for the pressure involved. To
stop firing up the engine all that's needed is to not trigger the
electronically controlled fuel injectors.

As a precaution, I decided to replace the 3V batteries in the remotes
as they were original (8 years old). Bugger me..they measured a decent
3.2V. In my books, that puts the amazing remote battery life up there
with the exhausts!!

Indeed..but it didn't seem like it. I was inside moving about (looking
at the miserable emergency start procedure) with the doors shut and
the alarm never triggered even when I opened the doors to get out so
the alarm and immobiliser might have been out of sync (good grief!)
but the doors and alarm weren't.

The little bugger did it again..just when I needed it for a school and
Gym (no no..not for me) run. Had to quick march to school to get the
little 'un - boy I'm not as fit as I was 30 years ago!!!

Anyway, the engine was warm so I figured it would start (as the last
time) after about half an hour so I didn't try and persuade it to go -
just gave up and left it. Sure enough, just as before, it fired up
after half an hour and got the little 'un to her Gym class which is
several miles away. It's unheard of for me to stall the 2.4
manoeuvring on the flat in a car park but the motor just died. Oh no I
thought - but it restarted just fine.

Armed with all this info, Google is suggesting the crank/rpm sensor is
quite a common failure on JTDs over 50,000 miles. I think I'll ask my
independent to "just change it".

I'll report back on progress..

Sounds likely to be some kind of sensor failing under heat.

It's a bit worrying. The more 'complicated' these cars get the more we
can expect this type of problem.

Remember those far of days when yer motor stopped functioning? Is it
fuel, is there a spark, etc.....before long you could be up and running
again. Now you need a computer and a mind like Einstein (spelling?)!

SteveH carries his around :)

FWIW even my bike needed it's brain lobotomised a while back. It just
would not start.
