accord
Have owned my accord now for about 4 months its a 2.2 icdti 2004 anyways I did three years of a mechanics apprenticeship before moving away from the trade. So I know my way around a car reasonably well.

So my car started to give out a lot of black smoke, cleaned the egr and all was fine then on the way home from the gym on monday the eml came on I plugged it into a code reader an the imrc came up. Cleaned that and its working fine now ( opening and closing the valave ) then on tuesday morning I started it and went to frive to work and had no power at all, with the pedal floored it was sitting at 1000 rpm spluttering and struggling to rev, then it started to clear and final revved right out,
So I tried to take of and it died, started it again and same thing got it to rev up and held the revs above 2000 rpm and took of and drove ok aslong as the engine revs are kept above 2000 rpm,
So I took my other car to work and left the accord in the drive,
Came home from work and wouldn't start eventually got it started. Still the same tho won't accerlate like normal untill over 2000 rpm. So I've tried bypassing the fuel filter to see and that has made no difference, I'm 90% sure thereno air in the fuel system etc
I'm not getting any smoke atall,

Do these have a low pressure fuel pump? Or just high pressure ?
Has anyone any tips or ideas the car wouldn't start today again so I'm thinking the fuel is running back to the tank maybe ?

Any help much appericated
Thanks aron
 
Welcome and EGR valve is jammed.
 
Would that cause it not to start and me having to use easy start to get it to start ? Also is their a good diy on this as If it is jammed I think I may have not cleaned it right the first time
 
Get it mapped out altogether give Fahad a call
 
Speak with Fahad mate. I had my egr deleted by him and my car runs great now. I started getting a little hesistation.
 
I'm in northern ireland though, the car seams as if its misfiring when you accerlate then when it reaches 2000 rpm it revs normal, and there is no black smoke or eml lights coming on anymore
 
Sounds like a big symptom for just the EGR valve, mine had hesitation under 2K revs but not anywhere near as bad as what you're describing - maybe if it siezes up completely you may get that though, I don't know enough about it.
Faddy can do a file only remap I think, you'd need to buy a lead to connect to the car (and some software?), but then the remap isn't for everyone, the other option is try to find a used EGR valve (unlikely) or buy a new one (£600 I think).
If you want to try cleaning again, there are a few DIYs on here:

The car would not start today so I had to prime and prime the pump, got it started and took it a drive went into limp mode and glow plug light flashing and gave the code p1237 I think this is something regrading the fuel pump? Also do these have a low pressure pump ? Mines is extremely low and I think I may have hit a stone maybe and wrecked the pump. I would jack it up and have a look but it's raining and I have to build a ramp just to get the jack under.

Thanks everyone for all you help
 
If you have someone with access to a Honda DIagnostic System you can run an EGR test which will tell you if its operating correctly. Sounds like a jammed EGR but it's always a guess from behind a computer screen mate.
 
I've ran live data on it and the egr something % is adusting it self up and down when revved up so I'm certain it's opening and closing, however the lowest percentage is 4% so maybe it is not closing correctly, I'm going more towards the fuelling end tho, it's the fact that the fuels draining back to the tank I'm hoping there is a lift pump on these cars and hopefully it's that or it's the relay or fuse which operates it, my theory is that the lift pump is not working when I get it started the high pressure pump is struggling to draw the fuel up from the tank then after 2000 rpm it creates it's own vacuum pressure and that's drawing the fuel. I'm going tommorow to buy a new fuel filter from Honda as I've read a lot about them a know I need a gienuine filter even tho I know it's not causing my problems


All help and contributions are greatly appericaitated
Thanks Aron
 
Just my tuppence worth... but I think these things only have a high pressure pump. And unlike the TDCI engine, they don't like to self bleed.

Have a look on the Lings Website as well as having a searchy here for how to get the real Honda Part Numbers.

Beyond that.... welcome to TA :D
 
As far as I'm aware there is no lift pump. That's why there's a priming bulb fitted.

It does sound very much like an air leak somewhere in the fuel system between the tank and the high pressure pump. Has any work been done on the car recently?

So today I was trying to get it started and removed the vac pipe going to the vnt accuator and hey presto it started fiest time and revs fine but when driving its like driving with no turbo, so I'm sure its what ever controls the valve which controls the vac for the vnt as soon as the pipe is reconnected the accuator lifts the bar which contorols the level into the turbo, so after messing arround and not getting anywhere and with nothing todo I ripped the turbo out and stripped it down and give it a good clean ill write a diy for the forum for other members. Anyways I have a slight suspesion the throttle position sensor or the crankshaft sensor may control this dose anyone know ?

As you do :lol:

Looking forward to the how to.

Hi

P1237 is a manufacurer specific DTC - these can be hard to find an explaination for, but I usually find these websites useful...

http://www.micro-tronik.com/faultcodes/obdiifaultcode_p1237.html
http://www.permoveo.ltd.uk/tabid/122/OBD-Error-Code/P1237/Diagnostics/Honda/Default.aspx

But, as you can see, there is disagreement on P1237 and other sites also suggest injector 1 might be faulty. So - in the absence of a known answer - it's a case of ruling out the things it can't be and I wouldn't expect a faulty turbo to cause a starting problem. I think it's a fuel supply issue. Good luck!

I am going to make a video of the car it hasn't been started and you will see just how bad this is and why my thoughts are that it's what ever controls the vent will upload it after I find the will to get out of bed
 
Correct me if I'm wrong but from what I am reading about the *** vnt turbos, the actuator is controlled by a solenoid which has three pipes, vac in, vac out and atmospheric pressure(goes to the air box) . However the accord only have to pipes vac in and vac out thus suggesting that something else monitors the atmospheric pressure a communicates this to the ecu which opens and closes the solienoid controlling the vnt actuator. My thoughts would be now that this would be the map sensor ?
 
Can you blank off your EGR with a little plate and see if it starts. I've seen P1237 before on a knackered EGR.

Most common things I've seen with these engines that result in not starting are blocked fuel filter, stuck EGR valve, dead/weak battery (even though it passes battery tests). And then yes issues such as knackered injectors can also cause non starting but very rare.

The only other thing it could be is the MAF sensor. Try disconnecting the MAF sensor and see if it starts - it will run default values with it disconnected.
 
I disconnected which I think is the map sensor (bolted on to the elbow going into the intake manifold and it starts fine and revs fine but is in limp mode.
 
Try removing and cleaning the map sensor.. did you also try removing thew maf sensor?
 
I had write a big post earlier but hasn't seamed to have posted, anyways I tried everything I could think of the stripped the loom back and found a broken wire, fixed that and the car ran like a dream just a slight hesistations before 2000 rpm so I cleaned the egr again and its cured that to. I'm going to get the egr mapped out completly, dose anyone know a good reputable company in northern ireland to do it. I have a tunning box I got of a friend but I'm not gona put it in going to go for a remapped can that be done at the same time as the egr delete ?
 
Fahad's the only one who can do a proper EGR delete, ask him what you need to do it remotely.
