Possible issue with crank position sensor
I have a related post from August time frame. Mine died during vacation. Cranked but wouldn't start. The battery was weak, and I replaced it. Real culprit was the crank position sensor. Once changed, fine ever since. Note that my truck would start after a period of sitting, but would stall shortly thereafter. If it does start for you (in limp home mode), be advised that it might stall again at any moment (if CPS is problem). A mechanic can change this $40 or $50 part in about 30 minutes, if you don't want to fool with it.
Good luck!

I second the Cran Positioning Sensor. They will go and you will lose spark since the ECU does not know when to fire the plugs anymore. Usually it is related to heat as well so as the sensor gets hot it quits. I would pull a plug off a wire and see if you have spark when cranking, if not I would definitely get a new CPS. They are fairly cheap and we all should be carrying a spare like an extra serp belt.

Thanks for the advice.
So I got a new battery.
The one in the vehicle was from Jan 07 and tested bad.
I put the battery in and it started up.
I drove up and down around the neighbourhood just to make sure all was well.
And nope.
The vehicle died.
So I'm attempting the the CPS.
Is this something I can order from Atlantic British, local autoparts store, etc.
And how hard is it to put in?

Rock Auto $60 - $80; British Pacific, Atlantic British, the list goes on.

Also from the RAVE:
That sounds like dealer time, but maybe not.
From RAVE:
The CKP sensor is located towards the rear of the engine below cylinder number 7, with its tip adjacent to the outer
circumference of the flywheel. The CKP sensor is the most important sensor on the vehicle and without its signal the
engine will not run. The signal produced by the CKP sensor allows the ECM to determine crankshaft angle and speed
of rotation. The ECM uses this information to calculate ignition timing and fuel injection timing.circumference of the flywheel. The CKP sensor is the most important sensor on the vehicle and without its signal the

Also from the RAVE:
Whenever a new crankshaft position sensor is fitted or the flywheel is removed, the adaptive values will have to be
reset, using TestBook.That sounds like dealer time, but maybe not.

I downloaded RAVE and found the "remove" and "refit" page.
The pictures make it look easy.
I'm sure it isn't.
I feel a knuckle scrap or two.
I see the references to "testbook".
I'm concluding this is some sort of diagnostic tool/programme?
Is this something I must have for this repair to be right?
Is it something I can/should get?
Am I stuck going to the garage?

Well, it is a fairly common item that pops up on the forum, but at the same time people are not being told to haul it to the dealer.
The testbook is a proprietary Rover program available to dealers and some independent shops, used to "talk" to the car and change some parameters in the ECU and other modules.
