Sorru without my heads in the engine i couldnt tell you ,but providing that everything is ok like timing belt and oil and water ect then what i do with these engines is too use a external fuel pump and pressurise the fuel from the outlet of the filter to the common rail pump ,often they get a air lock and defy all but you know who.musnt say god in case i offend the muslims or the jehovehs or somehting but that normally works ,now another tip depending on year and look in the intake pipe from the turbo to inlet manifold and see if your one has a sensor halfway along this pipe ,if it has remove it and make sure that it isnt full of oil as this stops it from starting and make sure their isnt excessive oil in the turbo pipe indicating that the turbo bearings are worn ,then the oil builds up in this pipe causing this sensor to not read stopping the engine from starting ,as for a crank sensor then never had one fail as yet ,its whats known as a hall sensor its just a coil that a reads a magnetic field ,and yes its favourite among a lot of get rich quick garages.Especially opel dealers on the zafiro/astra range of engines when it just the computer needs remapping as its bolted to the engine and get hot . But thats another story

    sorry no idea what a 58 plate means iam in spain and have been for the last 28 yrs .,have to think about this one again i think as its seems a bit strange it will not start ,look for this sensor in the pipe from the turbo ,in fact remove the pipe and check for oil --

Summary


Should a customer express concern about one of the following:


* hesitations,
* poor or no start,
* deteriorated fuel economy,
and upon investigation diagnostic trouble codes (DTC) P1412, P0490 and P1335 are stored in the powertrain control module (PCM), the probable cause is a sticky exhaust gas recirculation (EGR) valve.


To rectify this concern, a new EGR valve with a stronger EGR valve motor and revised PCM calibration should be installed.

My vehicle stopped dead at set of lights and would not start, called RACQ he installed new battery $165 Stated that was problem, drove less than 1/2 kilometre down road, felt the vehicle ****. Continued...


Sounds like you have a fuel issue. It could be a fuel pump cutting in and out. It could be fuel pressure regulator, or an injector not spraying correct. I think it's time to find an honest educated repairman.

Location of crank sensor on renault megane 1.6, 2004


bit confused...the cranksensor will be on the gearbox housing the camsensor will be near the cams not the gearbox if the camsensor has packed up it wont start but if it packs up while driving the engine will run untill you stop it then it wont start,a cranksensor could cause the engine to stop at anytime if it fails..your problem could be the idle air control valve or a timing related issue..
