Hi Everyone

OK. got pipes off filter this evening and managed to pump fuel through filter right away so blockage up to filter output. also took pipe off the fuel pipe and fuel came out there too. so I know fuel is getting to the pump. the filter looks orginal. but cannot confirm 100% unless I get it off.

Got my Diagnostic checker too today so put that on after I done the filter check thing..

Here are the 4 fault codes I got....

P0087 = Fuel Rail/System Pressure - Too Low
P1065 = Unidentified code
P16A4 = Unidentified code
P0088 = Fuel Rail/System Pressure - Too High

Anyone got any suggestions as for what I might need to do next..

Pumped priming pump loads to get it hard but it did go hard after about 5 pumps as fuel already present....

Cheers Gary
 
P1065 is fuel pressure lower than expected (so similar to P0087, but not identical).
P16a4 is an ECU internal error (quite common and is caused by low voltage conditions resulting from a flat/low car battery)

Codes could well be historic ones that are stored indefinitely, so need to be deleted and then see which ones come back and therefore relate to the current problem. P0088 is interesting and can - in my direct experience - is caused by a sticky fuel pump pressure regulator. I created a thread about this a few years ago, but I'm unable to put a link here.

Did you mean 'so blockage up to filter output'?
 
Hi Jon_G. Thanks for the heads up. Will clear the faults tomorrow night if I get a chance (work is getting in the way) and report back. No the fuel is free flowing all the way through to the fuel pump. Whats happening after the pump is anyones guess lol. but what I get out is clean and free flowing.

Will go have a look for sticky fuel pump pressure regulator now and see if its a job I'm happy to possibly tackle..... the fuel filter change is looking rather daunting... but as said above it looks genuine but without getting it off I cannot be sure.

Will report back asap.

Cheers Gary
 
Jon_G... Any idea where I need to look for your post. tried doing a search but came back empty lol.....
 
Did you search all forums for 'P0088'? I wouldn't suggest that to be the problem unless the P0088 DTC keeps returning. And making sure you have a genuine filter fitted is the most important thing (Bosch for PFL, Denso for facelift models)... P0087 and/or P1065 are classic indications of a fuel filter problem.
 
The fuel you are pumping could be going straight across the top of the filter, get a new filter if you have the pipes off then the rest of the job is easy. Where in essex are you?

Im in Wickford.....

All put back together again lol. Will get filter for weekend hopefully and have a tackle of it.... going to clear the faults off tonight when I get home and then see if the same faults come back and hopefully lessen the burden of trying to sort out the sticky fuel pump pressure regulator (if that is the problem)....

I must have the PFL version of car as my filter has the 2 bent pipes out the top of the filter.... Hopefully will get to visit Honda later today or tomorrow....

Cheers Gary

and the filter fits with the bleed screw nearest the fire wall.
 
OK. Been and got my fuel filter from Honda who also said for me to call Kent Diesel. which I did and they said for me to take the pipe off the end of the rail (end which has the bolt) and crank it over... Now the good bit is I cannot remember what next lol..

Cant remember if it was fuel out the end or no fuel out the end.. which means that the bit at the other end is stuck and needs replacing... got to now wait till tomorrow to call them back and ask lol......

Anyway. no fuel came out so to me that means no fuel is getting to the injectors. so none the wiser at present......

CHeers Gary
 
Oops.
Forgot to say. Cleared the faults down this evening and then re-checked but no fault codes came back..... have I done something wrong??? Tried starting car again to see if it would register them but still nothing lol.......

It means that those stored codes were historic, so may not have all related to the current problem. I'd still go ahead with fitting the fuel filter to see what happens. Odd that a Honda dealer would refer you to what I'm ***uming is an indy garage!
 
Hi.
Not fitted fuel filter yet. have it but can't fit till Saturday afternoon. Work and a toyota car service are getting in the way lol. Think they gave me the details cos they thought i knew what I was talking about lol.... told them about filter and the fault codes and said I know I can get the part from Bosch. they just gave me the phone number of the place where they get their bits from lol.

Not complaining. anyway. will fit filter Saturday and see what happens. I really do hope that this will cure the fault but I'm not sure it will.........

Will keep you posted about what Bosch guys say etc.

Cheers Gary
 
If it not this then do not bother to fit.

It is that one but not got the snazzy box..... just plucking up courage n enthusiasm to start changing.......lol
 
Filter is.out and it's a copy one. New genuine filter going in now. Fingers crossed
 
Ok. New genuine filter in and still don't start. Pump primed (30 pumps) but still zip.

No fault codes showing at all. At a loss now.....

cannot see any fuel leaks from any pipes and everything looks as it should....

anyone got any suggestions?????
 
So it was starting OK before? Was the old filter the same Bosch part?

From what it sounds like, the Bosch place (Kent) got you to check if the rail over-pressure relief valve was leaking - and it was. If they are getting you a replacement valve then hopefully that'll fix the problem. Bosch designed the fuel injection system and so those guys should know what they're doing. You did the right thing in changing the filter, but there is another problem that needs to be addressed, which hopefully will be when you replace the relief valve.
 
Hi Jon
no the old filter was not a bosch one. No markings what - so - ever.

Bosch guys wanted me to see if the relief valve was stuck open... or was it shut. And as far as I know everything was fine that end. No fuel was going back on the return path..... so no part ordered...

not sure what my next move is.... change the relief valve or go and do what you suggested in an earlier post and change the fuel pump pressure regulator..

or do I go and do both.. or do I go buy another fuel pump from.a breakers or eBay. Really not sure what to go and do. I'm lost....

Gary
 
could the immobiliser being playing silly buggers??? if so where is the fuse for it located... will remove and try to start..
 
I'm unaware of how the immobiliser might function in relation to the injection system and - in any case - I wouldn't expect pulling a fuse to prevent the immobiliser functioning.

Sorry I misunderstood about your pressure relief valve... it is apparently OK.

If it was me, I would next use some sort of 'easy start' spray (from Halfords, or wherever) into the air intake to see if you can overcome the hurdle of starting, and then see how well she runs once started (and if starting will be OK once freshly stopped).

When you primed the filter by pumping the bulb, you did also undo that 10mm bolt a few times to let the air out? Sorry to ask, but it is important.
 
No. Didn't undo the 10mm bolt.... I take it you mean the bleed bolt on rear of filter...... hope so Cos I'm gonna a go do that right now
 
No, not the rear (or bottom)... the top (metal) one.

You have to pump until the bulb goes hard, undo the bolt to let the air out, do the bolt up, pump again until hard and repeat all this until when you undo the bolt fuel comes out, but no air.

John's picture in post #18 of this thread clearly shows the bleed bolt.
 
OK. Undone the bolt and repumped the primer. 2 pumps and diesel came out so tightened back up. rock solid priming bulb went to restart and nothing. starter spins fine but no bite.........
 
OK, good luck.

Even if you bleed it quite well there's still a bit of air gets stuck in the pipes, meaning you may have to crank the starter for 30 or 40 seconds.
