Hey guys,
I know quite a few people right now are having problems with the CPS, and I wonder if mine is going as well.
Today I was out taking care of some "honey do's", one stop that I made, I was inside the store for about five minutes. When I went to leave my DII took about 4 secs of cranking to fire (it usually starts with a bump of the key). So this stuck in my head as odd, and stood out even more after reading about at least 3 other people having CPS problems. Does this sound like it could be the same?
My disco ended up doing this 3 times through the course of today, it was only when I had turned it off for about 5 minutes before restarting...if it was longer, like 10-20 minutes it started fine.
Speaking as one who just installed a new CKP, I think you/we have way to little empirical data to make a diagnosis. My 1996 D-I sometimes exhibits the same tendency, "hard re-start after brief stop" and the diagnosis is that I need new injectors. Injectors are not terribly expensive, but they are a pain to install. Explanation given was that they continue to leak fuel into the intake system following shut-down, causing a too-rich condition at re-start. Given a brief resting period, the fuel pressure bleeds all it's going to and the excess fuel evaporates. If I can get mine to start after one of these situations, brief stop following a 30 minute trip, I have to continually feather the throttle until the excess fuel burns off and the engine runs smoothly.
In the case of Lucy's CKP failure; car stalled while stopped at a light was pushed to the side of the road and after about a 30 minute wait, while I drove to her rescue, the Discovery II started and got her home just fine. Next morning, no start at all. I followed the RAVE manual, advice from the forum and ruled out, IFS, Fuel pump relay, fuses, fuel pump and replaced the CKP. All is well since the change...
Good luck with your discovery and repair.

As far as injectors go... is that something that starts to go bad over time? I'm the original owner of this disco, and yesterday's hard starts were the first time that this has ever happened in my almost 11 years of driving it. I'll go through my records and see if injectors have ever been worked on.
There was no fuel smell that I noticed, and I really don't think that I looked at the tach. I had more of a deer in the headlights reaction to what was happening
It never fail to start luckily, it just took a few seconds, when I'm used to an immediate start when I turn the key.
One thing I did notice, and I'm not sure if this means anything...it seemed to crank super, super fast. I can't say if that's normal or not since like I said, it usually starts immediately. It's just something that stood out to me.
I plan on trying to recreate the situation today and I'll look at the tach if it happens.
And I want to give a big thank you to everyone on this forum! Up until just a week ago I would have gone straight to the dealer with this.
And Voyageur, my back hurts just thinking about having to push a disco to the side of the road!
Injectors typically don't get worked on, they may charge you for cleaning them. If they go bad you replace them, there are also o rings that can be replaced on the injectors. It would be unusual for all injectors to go bad at the same time, its usually one at a time - unless you get some serious dirt in your gas that blocks them all up.
Indeed injectors can degrade slowly as leak progresses. Could be one injector leaking and seven good. Rapid turn-over may in fact be due to the surplus fuel in the system. Similar to starting a carb equipped engine with foot slightly on the throttle.
As you stated the forum is usually very helpful. It is also a great idea to download a RAVE copy of the Discovery II Workshop manual. It is free...
Computer controlled "anythings" are certainly prone to unusual behavior, based on no recognizable input. That is why vehicles are usually referred to as "She" or "Her". You know... "I just can't get her to run.""I don't understand it she just quit on me." Hey, hey hold on all you angry, women, Landy owners... I have been married to the same "SHE" for 43 years... Our D-II engines are receiving input from 23 different sources (Sensors) anytime they are running. Amazing "She" does so well most of the time...
"Juicy Lucy"... My "She"...
PS: My back isn't sore from pushing "Her" 'Overy because two handsome studs had already stopped and removed her vehicle from harms way, by the time I got to her...

Sea Foam is great stuff... I suppose it is possible that the SF loosened up some deposits that are still working their way through the system. The Sea Foam Rep, who I buy mine from, said to use it whenever I have at least a 30 minute un-interrupted trip planned. I normally pour mine in just before we head out on a trip that I expect to last 60 minutes or more. I also use the "Spray Can Type" Sea Foam Injection cleaner and it seems to do a good job. My injection system is plenty clean it's just leaking fuel. Soon to be remedied...

SF in a full tank normally has no ill effect. Take it out on the highway and burn out the cobwebs and see if the problem clears up. I agree with Voyageur, maybe some gunk was knocked loose and just needs to be burned out.
Well I wasn't able to duplicate it today, hopefully it has resolved itself.
Would it be advisable to just go ahead and replace the CPS for peace of mind? I'm sitting at 147k and don't see in my records that it has ever been replaced...
James... if money were no object I would buy a new Land Rover every year and then I would know I had all new parts. Trouble is the only friends I have with "New" Land Rovers are having all kinds of trouble.
I can't speak to how common failure is. The part is not expensive and if you can get it up on a lift it isn't hard to change. If it were to fail on a trip and you had to do it under a Hi Lift jack, that would suck. Blah blah blah. I know I talk too much.
If you already bought it and you can stick the new one on - it can't hurt.

Voyageur, I have not bought one yet, just looking at stopping a problem before it happens, if it is the CPS causing the random hard starts. Then again I believe in the whole "if it's not broken, don't fix it" or of course there's the LR quote of "if it's not broken, it must not be a land rover".
The gunk being knocked loose from the fuel system sounds like a pretty dx though.
It's like a what,a $60 part? If we could call it preventive maintenance it would be worth it to avoid having the truck dead in a parking lot or side of the road.
Your comment about new LR's having problems worries me though....my better half has informed me that she will get a new BMW X3 for her birthday.
So it has been decided that santa will bring me an LR4. What have I gotten myself into?

You should change out the CkPS before it decides to dump while you are 80 miles from now where and your triple AAA has expired. If are having these issues it is the beggining of the end for your sensor.
AND I think somoeone owes me $20??? Is now a good time for a big fat "I told you so?"
Ok, replace the CPS it is.
Next question.....
I have always gone to the LR dealer for everything on this truck ( I know, I know...hadn't looked into fixing it myself ever), and I'm looking for an honest opinion on this. Do I get the part from the LR dealer, or is it acceptable to replace with one from an aftermarket store like autozone, advance, napa.
Is this like the MAF where it has to be genuine in order to function properly?
