Ive got a 306 HDI turbo diesel and it will not start even though the fuel pump is working?
Answers:
You have a blown head gasket, your pistons have had it, the injectors are worn & the valves have bent.
Join the RAC or AA, or get it to a garage. Have you tried bump starting it?
Well you've gotta check and make sure you've got spark, you've gotta make sure your battery is charged, the starter is working, all fuses aren't blown, all of the sires are good. And that's just for starters.
If the heat elements are working then it must be either a fuel problem (no one's put petrol in incorrectly?) or the computer thinks one of the components isn't working.
Are you using the same key? If the sensor in it is missing, the car won't start.
Sounds like a garage job otherwise.
Have you changed anything on the engine if so it could be a timing fault.
Faulty injectors
faulty glo plugs
Wrong fuel
Faulty Immobilser
There is quite a list so need more info
it could be your alternator or battery or you could have an immobaliser and the key you are using isnt the right one
crack the nuts off on top of the injectors see how much fuel there is comming out when engine is swung over if plenty of fuel engine should start or got blocked injectors.posted by mechanic
when it worked before did it have a water leak or anything if so it may have pressurised and you may have a airlock in the pipes now.
when you try and start it does it try and start if it does buy some quick start and open your air box and spray some in then try and start it. If it starts this way it maybe that your glow plug maybe broke or u may have a blocked or damaged injector.
MORE DETAILS WOULD BE BETTER TO ESTABLISH WHAT IS WRONG WITH IT.
Which fuel pump have you checked? The low-pressure pump that brings the fuel up from the tank to the high-pressure pump, or the high-pressure pump that feeds the common-rail and the injectors?
Is there a fuel cut-off switch somewhere? These cut the fuel in case of an accident, but can occasionally be knocked by another action (I've know it to happen when vacuuming the interior, or by a speed-bump in a car park). They're easy to reset by pressing the button (check the manual, I don't know if you have one or not).
Is the immobiliser definitely recognising your key? There's probably a flashing red light somewhere on the dashboard that should go out when you put the key in the ignition. If it stays flashing, then you'll probably need to get the car reprogrammed to the key.
suonds like the imobillisor not switching off take to auto electrician/diagnostic engineer to see if key needs reprogrammed.dearer option is to go to pug dealer
