Dear all, Sorry for the long post..

This is driving me mad.
I have a 2001 75 CDT Con SE, with the warm/hot starting problem
Starts cold 1st time, but run it for a while, jump out, get back in and it turns over and over. Its been doing it for a week or so but got worse today and left me stranded outside a shop for 10 mins until it eventually started.

I've read all the posts about it most likely being the cam sensor, i've taken it out and had a look, but its not , much to look at really and not servicable.

I dont suppose you fine people know how to test it or better still, have one lying around i could borrow and buy ?

Hopefully someone can help

Sorry for the long post

Steve

How much do these things cost? surely not an arm and a leg why not just go buy another one at least that gets it out of the way and if the problem continues you have one less area to look at?

Fingers crossed, keep us posted, and if it does not work put the other one on Ebay use the word "Rare" you should get your money back going by the feeding frenzy on rover bits on Ebay currently :)

I might put myself up for auction in that case!

I said 'Rare' not 'Ron'!
Dunno about up there in the frozen wastes but we have got plenty of Rons around here already

What you ought to do is try flogging water to them down South

I keep thinking of putting my Pond on Ebay (buyer collects of course) and I will supply a bucket if required :)

Electric fence is to keep my dogs out btw and the thing in the centre is an old picnic table on floats which the ducks love to sit on

Look nice.

I wish I had bought shares in a water butt manufacturer, apparently they're going like hot cakes on Ebay...

Cam Sensor

Hi guys,
Just to keep u informed, i got the new cam sensor on saturday morning, fitted it and left the car running for 10 mins or so to let it warm up. Turned off the engine, waited a minute or two and low and behold, it just turned and turned but didnt start, so it wasnt the cam sensor.. I'm at a loss now and looks like im going to have to take it to a rover dealer, unless anyone can give me another suggestion.

Steve,

Thanks for a great thread.
My car has exactly the same problem and have only last week had the fuel pump and number one fuel injector replaced with no improvement.

I was about to try the cam sensor and I am wondering now if it is really worth it.

My car has been to an ex Rover dealer and they diagnosed 'spilling back through number one injector'. This has now been replaced and the fault is still there.

I am relying on a spray of 'easy start' into the air intake to get my car going at the moment.

Let me know if you manage to sort your problem.

Regards

Tim

That only leaves the crankshaft sensor!

It is strange that it runs okay once its started with easy start. This would tend to rule out the crank sensor in your case, but maybe not in Steve's.

Can I suggest that you both try unplugging the fuel rail pressure sensor and cleaning the contacts, or even removing it and checking the orifice.

You could also try leaving it unplugged and see if the engine starts.

Its below the arrow in photo five on my 75 home page here:

http://45zs.info/75Zt/R75home.htm

Just remove the engine cover, and the intake duct to make access easier.

(You don't need to remove the duct completely, just undo the two screws that hold it onto the inlet manifold and then pull it forward against the corrugations so you can detach the end that connects to the air filter housing.)

Its 27mm across the flats if you want to remove it. Don't be surprised if it seems loose - this is not uncommon.

Photo 5 is the one with the orange arrow pointing to the approximate location of the sensor.

The cranks sensor is just above the left hand end of the starter motor - 3 wires.

Cam Sensor

Some more information,
I've just been out trying to start the car again, trying to see if i can put a pattern to it, before i buy a crank sensor or book it into a dealers.
It seems, when you turn the ignition on, to when the glow plug light is shown, i can hear a buzz coming from the engine, when the buzz is audible, the car starts. If i take the key out of the ignition, wait a second, then turn the ignition on, theres no buzz and the car doesnt start, just turns and turns.. no revs apperaing on the rev counter either..
If i play around, turning it off and on again , the buzz comes back and the car starts..
Even more curious.. could it be an immboliser issue ?
Hope this makes some sense

Is the Buzz is coming from the low pressure fuel pump next to the battery, if so then that is probably normal it will sometimes run for a few seconds with the ignition on but not always

cam sensor

Keith,
Yes the buzz is from the fuel pump, if it isnt buizzing the car wont start, if it does buzz when the ignition is on the car does start, does that make sense ?

Is it not meant to activate everytime the ignition is turned on ?
The car has the new cam sensor fitted, is it worth getting a crank sensor ?
