cold start problems on my HDi

[pat]

Bleeding the fuel system is not necessary, it will bleed itself during cranking, it just takes longer to start. Be careful if you renew the washer under your injector. The old one can stay behind in the injector hole and can be difficult to remove. Also the tigthening torque of the injector clamp bolt must be set at the rigth value otherwise it will start leaking again or you can damage the thread in your cylinder head. The leaking washer so could be the cause for a bad starting engine because you loose compression due to this leak.

Every petrol station is selling winter diesel during winter time, I wouldn't be too concerned about that. Only if the temperature is dropping below -20 C this could be a problem. Until - 10 C a HDI can be started without glowing, during starting the glow plugs are activated as well, without the ligth in the dash is coming on, so you will not be aware of that.

Pat, you seem to have good knowledge and experience of the fuel system on an HDI - me thinks you will be very helpful around here

yes, get rid of any air that might get into system whilst changin over pump. My fan belt is screeching aswell. At least i no what to look out for in future. I purchased the car in the summer/warmer weather should i say, so it was ok at starting then.

[jamie69]

ye, if i change over the pump wont air get into the system?
where can i get one of these washers? do i have to buy a whole new injector?
thanks

A new copper washer you can buy at the Peugeot dealer of autopart shop. If you change over the pump, air will get into the system. When you have installed the new pump during starting the engine, the air will be pushed out, starting will take longer therefore (15-20 sec).

I would not advise a diy person to mess with HDi injectors, it can be very dangerous.

See how your starting is when you change your battery.

Replacing or removing an injector isn't that dangerous, as long as you know what you are doing. I would never advise an unexperienced person to fiddle around the car, but almost anyone can learn. If you're not sure about your knowledge, try to get the help from a more experienced person.

With respect, the problem is the high pressure that the injector works at that worries me, it can be very dangerous.

The actual mechanics of removing and fitting the copper seal is fairly simple.

Wouidnt the injector have to be out and still plumbed in for it to cause injury,
ive heard the Spray from them can be fatal and heard of people having holes blown through there fingers,


ive cracked off injectors in the past too bleed them and ive never had any problems,

[jamie69]

sorted. My battery was nakerd. Thanks for the advice. I can bare it in mind should i get another diesel at some stage

The last winter (-15 degrees) killed a lot of batteries.
Diesels seem to take a huge strain on starting.
My dads diesel Nissan Navara works van needed a new heavy duty one, looked like something out of a Prius

It's due to the compression ratio - diesels are generally nearly twice as high as them noisey, sparky, fings.

Also to get enough compression for ignition, you need a reasonable cranking speed......

[pat]

It's also the engine speed during starting which can give problems with a HDI. It needs to be above a certain speed or the computer will not start to inject. Therefore it is important to have a good battery and starter motor, otherwise the engine speed will be to low and will not start.
