|v4vendetta||i am also having problems with a injector seal that is starting to blow a little is there a link? as described in the above posts?|

Replacing an injector can be a chore, as the old ones can be a pig to get out.
I've had all mine out (when replacing the timing chains), this is how I did it (post 7 of this thread)... Diesel Injector Removal - Diesel Faults - TypeAccord
You have to be a bit careful when refitting to make sure that the seat is properly cleaned up (see post 67 of this thread)... Injector issues - Page 4 - Diesel Faults - TypeAccord ...Ideally use a new copper injector gasket (seal), or at least re-anneal the old one. Subsequent leaks are not uncommon!
If you fit a different injector then the 6-digit IQA code on the top of the injector will need to be entered into the ECU using an appropriate system (HDS is ideal, but other garage diagnostic equipment can do this). If you don't do this then there'll be an imbalance that will affect performance (the ECU will self-trim to a limited degree, so you will be ok to drive it around until you can get the code entered).
Good luck with it.

|Chris1977||Jon the codes where 2 to do with fuel rail pressure and the other one was glow plug malfunction. Al find where i jad them wrote down somewhere anyway didthe leak back test today and you where right one of the injectors has excessive leak back problems ordered new injector hopfully when it comes al be back reporting all is ok cheers.|

You say the EML is coming on, it would be useful to know what Diagnostic Trouble Code (DTC) is being stored, although I still think excessive injector leak back is your problem.
As said, the glow plug warning light coming on when the engine running does not relate to a glow plug problem. Despite this not being mentioned anywhere in the Bosch manuals, it is a 'heads up' early warning that the ECU is experiencing a pending DTC (usually relating to fuel pressure, in my experience).

|Chris1977||Jon ave just realised aswell that the earth strap to battery is only holding on by a few strands of wire this wont be causing problems will it?|

|Chris1977||What a will do here is give the symptoms am experiencing at mo,when a start car in morning engine management light is on! and car is in limp mode, when a drive the car for a cpl of mile the the glow plug light will start to flash on and of,Then the car wont start when its hot, it will how ever start with easy start and even go out of limp mode but soon as easy start is burned away its straight back in limp mode. One thing is for sure a wouldnt waste my time with honda dealership who tryed to tell me that the ecu was knacked or a break in wireing for the glow plugs, instead of finding out why the fuel rail pressure is low as am sure the ecu is stop sending a signal to glow plugs when car is hot after dectecting theres a problem to stop damage been done to the engine|

|Chris1977||Cheers zero, yeah i have worked that out about the glow plug light shame honda havent realised this about there own car. Anyway am with jon on this am still to do the injector leak back test which am going to do today but after changing the over pressure valve and then checking it to make sure diesel seems to be pumping back out the metal nosel bit. As jon said a little bit is normal but its spirting out of the now so hopfully i find out which injector(s)it is today.|

I had the engine glow plugs light stay on and it turned out to be the engine fan cooler control at the bottom of the engine. This I didn't find out until after changing the glow plugs. The mechanic that fixed it for me said that the glow plug light on the Honda isn't necessarily about the glow plugs. Before getting the fan fix I did manage to get the glow plugs light to p-off , was annoyed it stayed on after changing the glow plugs, by using an after-market ODB connector and clearing the faults, but, this isn't recommended as it hosed my built in hands free bluetooth.
Hope this helps!

|Jon_G||This guy did his Accord a while back and made a few posts on this forum... http://www.civinfo.com/forum/honda-a...ml#post3402921|

|Chris1977||Thanks john ave looked on you tube al test the injectors at the weekend. Aye honda was saying it was ecu or a wire lose to it for glow plugs, a did say do u not think its bringing glow plug problem because ecu is detecting a problem when its been running there for its not sending signal to glow plugs to stop damaging engine. but honest got no confidence in honda and when a spoke to technician and told them how a tested the relief valve he was struggling to understand the return from fuel rail and how a tested it.|

I personally think you have an injector with an excessive leak-back condition, so definitely ask for an injector leak back test to be performed. If it's confirmed, then hopefully they can fit a secondhand injector to keep the costs down (a replacement injector should then have it's calibration/IQA code entered into the car ECU). I really can't see how it's the ECU, not now it starts OK when cold.

|Chris1977||A dont no where i am on this site lol ave just msged u sumwhere else honda trying to say they cannit find it same codes coming up glow plug problem and fuel rail pressure. At first they didnt have clue now they saying lose wire to relay or the ecu is knacked and to cut my losses and get a new car. Pritty pee'd of now sick of it. So u think a should try a diesel specialist?|

That pipework also carries the returns from the injector leak-backs to the fuel tank. So it is normal that fuel WILL come out of that pipe if it's pulled off!
But a large amount of fuel coming out, in conjunction with poor warm starting points to at least one injector suffering an excessive leak-back problem (another fairly common problem). A diesel specialist could easily re-route the injector leak-back into containers to find which one is excessive (in fact it's a pretty easy DIY).
I'd strongly advise that you use a diesel specialist, rather than a Honda dealer... a Honda dealer will not have the same experience of these problems and may simply replace all the injectors, which will cost you over £1500!

|Chris1977||Hi joh it now starts with the key when cold but not warm checked the new relief vavle a put in and no diesel coming out now. But when a take the braded pipe of altho its not coming out that end it seems to be pumping out the metal stub, back into the fuel rail in other words ( should it do that with it soppost to bethe return) if u look at the picture how to test the valve u will understand what a mean. Anyway its going to a honda garage tomorrow so will find out what they say cheers.|

Great news Chris.
By the way, once an engine problem has been corrected then the engine warning light will go off itself after 3 warm up/cool down engine cycles OR you can disconnect the battery negative for 20 minutes to force a reset (but the code wil stilll remain stored on the ECU so yeah, best to have it properly deleted using an obd2 scanner).
|22nd January 2017 13:02|
|Chris1977||Hi jon ave managed to get that relief valve and changed it the car is starting straight away now. The engine managment light is still on so am waiting on a friend to delete the codes for and hopfully thats it. A big thank you for your help its much appreciated al right back once codes are deleted to hopefully say all is well, cheers|
