Honda CR-V 2.2 CTDI - Will not start when it is hot outside - maza

My wife bought a Honda CR-V in September. 09 2 owners 61,000miles. It has now strted not starting when the temperature is over 22' outside. The RAC said it might be the fuel pump. The garage who supplied the car have now quoted over £2,000 for a new fuel pump and injectors. Is this a known fault and any ideas, please?

Hi

I would get a 2nd opinion. It could just be one or more leaking injectors, seams odd to be both.

I have had this problem on PSA engines due to the filter in the pressure regulator valve on the HP pump but no idea if yours uses the same one. Take it to a diesel specialist rather than a garage, they usually know what they are doing and just replace the faulty part and not everything else as well.

In my experience, I think it's quite likely that the garage which quoted the £2000, not being a diesel specialist themselves, will not do any work at all on the car. They'll charge the £2000 but take the car to the local diesel specialist and let them sort it out! They'll probably pay less than 1k to the specialist, and make a big profit for themseves!

Top Dead Centre (TDC) sensor is a common fault and will not show up in fault codes (- it works when cold).

The numpties you are dealing with are a danger to your wallet.

Go to a diesel engine specialist...

Meanwhile Google " Honda diesel warm will not start" and read.

I reckon TDC sensor..- and it's a CHEAP fix ... £250 tops incl labour - may be less.

Of course you could take it to a Honda dealer who might know straight away what the problem is rather than using guesswork.

Edit - I have just checked some information and your symptoms are indicating a failed or failing fuel rail overpressure valve.

The following is from the Civinfo forum (same engine) How to diagnose:-

Look at the engine. The fuel rail is the tube with several brass nuts with narrow metal tubes (fuel lines) attached. To the left hand end of the tube, easily missed, is what appears to be a 17mm bolt. Close by is a black braided flexible tubing (low pressure fuel return pipe).

With the engine off, disconnect/pull off the black braided hose, you may need a flat bladed screwdriver to get this started. Attach PVC tubing to the end of the braided tube, seal with adhesive tape, put other end of PVC tubing into container. A 1pt milk bottle seemed to rest quite neatly in the engine bay. Place rags under the tubing and the now exposed metal tube.

Turn over the engine for about 10-15seconds. Return to the engine bay and inspect the container. If diesel is present either in the tube or in the container the over pressure relief valve is most likely to be faulty.
