Car Forum / Peugeot Cars / February 2008Cold Starting probelms
Hello to all Can anyone advise on likely causes for non start of the 2.0 HDi I have replaced all glow plugs with new and it was working fine for several weeks but then would not start. It seems that if the air is very damp it won't start. I have an electric fan heater which I put under the bonnet for about 20mins - it will start after this. I don't think that the heater imparts enough heat to the engine to make the head warm enough to allow the engine to start - could it be that the heater dries out the air in the intake and this solves the problem? The external temp sensor reports temp OK - is there another sensor looking at cold/humidity etc that could cause this? Next stop is a new preheat control box but I am not convinced this will resolve the problem Any help gratefully received. Many thanks Andrew many things as haynes says,air filter element dirty or clogged.wax formed in fuel line. air in fuel system. injection pump timing incorrect.preheating system fault.thats some of the things in the book.. sorry i try again.

Air in fuel line is also unlikely if it has a Bosch system. (fuel lift pump gives something like 3 bars pressure, so any problem would result in fuel leakage). The HDI engine has so many electronic bits controlling it that fault finding is difficult, and really the only way forward is to get a readout of the fault codes. So its got to go on a machine to find fault.in other words, > So its got to go on a machine to find fault.in other words, It doesn't necessarily mean a Pug agent though. Most repairers have the hand held gadgets that can download the messages, my excellent one man business guy certainly has.

I did have one till i left it out one night and it got very wet . >I did have one till i left it out one night and it got very wet . They don't respond well to that sort of treatment do they ;o) Keith It did not work at all after that , but got to buy new one .. one day > > So its got to go on a machine to find fault.in other words, > [quoted text clipped - 3 lines] > -- > Keith Willcocks Certainly you don't need to go to a main dealer, but there are problems with connecting to Pugs, and many of the low end readers do not work on some models, depending on the year. Something to do with the introduction of multiplex wiring. However, ones like the Dec Superscan, and Sykes ACR4 work fine, and can even reset warnings about additive level low. try give an starting aid. and be sure that you use battery with CCA sorry, my english bad. |
