My Grand Cherokee (2003) 2.7 CRD has started suffering from some starting issues over the last four weeks or so, and I was wondering if anyone might be able to point me in a direction for trouble shooting.  What Ive noticed is it takes quite a lot of engine cranking (sometimes as much as 30 seconds) and I have to put the accelerator pedal hard to the floor to get it to fire.  Essentially, it doesnt matter if its a cold day, or if the Jeep has been standing over night, or if its just done a 300 mile trip or just a short trip down the local shops, its the same each time.  Once its started though, I have no problems at all, it idles steadily and I have no lack of power or stuttering.

So far I have checked the car for fault codes (both with the key trick and an OBDII machine), but nothing comes up.  I've stuck a bottle of STP diesel engine cleaner in, and am going to swap out the glow plugs (the Jeeps done nearly 70k and I'm guessing they are the originals) so probably worth doing anyway.  The fuel filter was changed about 15k ago (long before these issues appeared), but I'll change this again just in case.  I'll also do an engine flush and change the oil and filter.  Hopefully all this will take care of anything related to carbon build ups or crap in the engine.

Can anyone suggest anything else that might be the culprit for causing this, or has anyone experienced anything similar before?

Thanks very much

have you checked the air filter . is it turning over as fast as it should ?  What about the electric stop on the pump it could be sticking have you tried turning the ignition on for 30 or 60 seconds before you try to crank

one of the injectors are duff 
needs a bleed off test, to find out which one.
doo
do a search on here, for crd strife

[gregwho]

Thanks both Joe and Daggie for your replies.

Joe, I'll also swap out the air filter just in case (its not a very expensive part so could be worth doing just in case).  I haven't checked to see if leaving the ignition on for a while before cranking will solve it, so i'll give that a go later.

I did do search for "crd strife" and only returned your reply on this posting - should I look for a different title?
Cheers guys

theres loads back on the tech forum

It won't.  You need to attach pipes to the top of each of the injectors and put the other ends into cups (I used the lids of grease sprays) and then crank the engine.  It's likely that one or more of the injectors will fill the cup with diesel fast, the other non fucked ones will pump some out, but it's unlikely any will end up in the cups.  If you need pipe, go to Halfrauds and get some clear plastic pipe, cut it to length and find 5 recepticles (I've never used that word in a post before) then try it.

When you find the fucked one(s) go to uniteddiesel.co.uk, ask for Keith and give him the part you need (098) then swap them out, make sure you get the seals (Keith always supplies them) and some grease, and clean the seats too.

Fit the new injector(s), then start

Cheers MudSurfer, off the back of Daggies post, I did a general CRD search...holy hell there have been some problems reported, but nothing compares to a posting you did a few months ago with the trouble you had, and how you got it resolved.  I didnt want to revise an old thread by posting there, but just wanted to say "awesome work you did with finding the problem and getting it fixed"!!  There was a great posting from Dutch as well that explains the fuel delivery system which is useful to know. 

So, as you predicted leaving the ignition on before cranking didnt help, which I guess leaves me at the point of knowing that one (or more!) of my injectors is starting to cause a problem.  Would you say that the issues i've got (which definitely arent as severe as the ones you had) are the start of injectors going wrong, and that as time goes on it will only get worse?  From the manual it says to get to the injectors 4 and 5 you have to lower the engine...is that as bad as it sounds?  Ive only got a driveway to work on the car and I guess if its a fecker of a job, I might have to relent to finding a local garage...which I really dont want to do if i can help it

Here is a link to how i changed the injector seals , same steps as changing injectors I did it on the drive with basic tools , hope it helps

TBH
I have most tools and the knowhow to do most things
I would take it to a BOSCH diesel service center, basicaly to save a lot of fucking about
1, the have all the gear
2, if it won't start after you've changed the injector,it will need to be hooked up to a computer, mine did 
3, it would be good practice to re-cut the injector seat, then re-torque using a new bolt.they have the cutter.
4, if its the rear two injectors, they are cunts.
5, let them swear and get diesel everywhere


it cost me 340 squids to do 2 injectors & three seat cuts

+1

Do not have the know how, let alone the skills

Had all 5 done by my (non-Jeep) garage. Nbr. 2 was leaking but we did them all  £400' ish

One started leaking again after 9 months....no probs.....fixed under guarantee

No hassle 

[gregwho]

Your list rang home, particularly numbers:

4, if its the rear two injectors, they are cunts.
5, let them swear and get diesel everywhere

TBH, number 4 on its own probably would have done it 

Ok, so I think its a safe bet to say Ive got some injector issues, either bad seals, leaks or just knackered injectors.  Quick question if I may...when you guys found you had leaks, was there any visible sign of this, or was it just that you got it checked on the correct equipment which found the fault?  I'll do a google and find out where my nearest Bosch diesel service centre is, unless anyone happens to know of one around the Aldershot/Farnborough area....

Cheers again all for your help and much respect to those who have fixed their issues without needing dealers, garages and the like

Leaking on mine was pretty obvious.

First you get this specific aroma through the airvents.

Better have a look......Yep, the black death around a leaking injector is ...... unmissable.

Mind you, did not have any performance drop or fuel issues. It is just that you may damage the injector itself
if you leave it unattended for a length of time.

I recently had two injectors replaced and the symptoms were just the same. I got a local garage to do it as it was number 3 & 4 which clearly showed up on the leak off test, that had gone so the engine had to be dropped. I also got the garage to take out number 5 and put the two new ones in to 4 & 5, cost a little extra but at least the engine won't have to be dropped again in a hurry (I hope).

Mother in Law has a CRD, she had been using it and had problems starting.

Whilst my V8 was in for its Gas conversion I borrowed hers and whilst at traffic lights has smoke pouring under the bonnet.

Diesel was spurting out the injector seal and burning on the hot engine, When I spoke to her she said it had smelt funny!!!

Went to the garage that did my conversion and it was injectors 1 and 2 the seals had gone, (retard of an AA man removed them to fault find after she ran out of diesel).

Cost was less than £100.
