Hi I've recently bought a 2006 2.2 I cdti Accord tourer with 150k on the clock, the car starts fine from cold and runs really well but after stoping and trying to restart it takes a lot longer to start it always starts again but how long this will last I do not know. Any ideas thanks Nick

This is usually the fuel rail over-pressure valve is leaking, which prevents the fuel pump being able to raise fuel pressure to the 200 bar minimum at cranking speed. This is the best thread on the subject, but unfortunately the initial pictures are missing... http://www.civinfo.c...2-2-i-ctdi.html

Basically there is a valve on the driver's side end of the fuel rail that should never be passing fuel... You need to remove it's discharge pipe (and block that loose pipe) then reroute the valve discharge into a container to see if fuel is flowing out. If it is, then a new Bosch valve can be bought from eBay for less than £100. If the valve isn't leaking (which is a common fault) then the other possibility is one or more of the fuel injectors has an excessive leak-back flow - actually another easyish DIY test, but definitely check the rail over-pressure valve first!

Will do I'm doing the test over this weekend I will be extremely happy if it is the pressure valve as I love the car to bits.

Update on fuel pressure valve. I did the test today and diesel pasted through the valve almost as it was a fuel pump itself. I put a pipe on the valve outlet into a cup and started the car, immediately fuel poured up the pipe and into the cup so I'm assuming it's nackered . I will order one and get it fitted and hopefully that will be the end of my problems, the only thing to note was I tried to loosen the valve bolt with a ring spanner and not a chance it's ****** tight and can't get a socket on it. There is a pulley wheel held on with two bolts that if removed could give more access I might just let my local garage to do it as they are very reasonable price wise . Thanks to Jon g for advice.

If fuel was coming out of the metal outlet on the fuel rail then there's your problem! It should only ever pass fuel in the event that the fuel rail over-pressurises due to a fault condition.

 

They are usually reported to be very tight to shift, but decent tools go a long way to making it a reasonable DIY. You'll save money AND feel like a hero if you fix it yourself, but don't skimp on the tools if you need to buy decent spanners or sockets (6-point are better for tight nuts in an awkward location, I think it's a 17mm AF but do check by trying a spanner on it for positive confirmation).

 

Either way, please let us know when it's fixed.

Hi final update on my problem, I'm pleased to report valve turned up today it cost £92 from a deisel specialist I also bought a six point 17 mm spanner to loosen bolt. I fitted valve and​ the car now works perfectly , it seems to accelerate slot better and now starts spot on when hot. Thanks again for the advice I'm sure I will be using the forum slot more in the future.
