    Default Diesel no start

    My 1.6l diesel C4 has been sitting for some months and won't start. I have plenty of herbs in the battery and diesel is present at the junction at the top las of the motor. Do I need to keep squeezing the manual pump at the top of the motor or is there some other potential issue I need to be aware of?

    You might get more suggestions on the Citroen Forum. Have you locked and unlocked the car using the remote control a few times? Also try turning the ignition off, wait 30 minutes and disconnect the battery for 30 minutes. Then reconnect, lock and unlock the car and try again.

    If those tricks don't work, you might have to start checking if the lift pump in the tank is getting power and working.

    How long is it since you ran the car or filled it up with fresh fuel? Is the diesel fuel still good or has it blocked the fuel filter?

    Cheers, Ken

    These are always tricky after a fuel filter replacement

    The fuel is being pumped to the junction at the top of the motor so that point is eliminated. Is there such an animal as fresh diesel. I understand with my rudimentary knowledge of petrol that the volatiles can evaporate.

    Yes Beano,

    That thought had occurred to me too. I just went down and checked my can of Start Ya Bars...d that I use regularly for the motor mower and wipper snipper and there are instructions for diesel engines although it says to disable the glow plugs.

    Cheers, Ken

    You fellows just want to blow my motor up just for the fun of it! Actually if I can't get the gearbox going I might follow the various highly volatile suggestions. I will report back next week after I try David's less dramatic suggestion of pumping the c**p out of the rubber pump while applying ignition (?)

    Sometimes a bit of ether just gets the whole process happening, at least for petrol engines. I confess that I know very little about diesels, but that principle still holds true.

    Please do remember to disable the glow plugs though...

    You need to remember the compression and the small amount of fuel a 1.6 diesel has easy to over fuel and bend a rod last time I took a cam belt off one of these it was for aerostart

    ^ Do you mean that the engine was trying to compress the liquid diesel fuel ? Diesel 4WDs sure are prone to engine damage from sucking in water.....but hang on a tic....you said it was caused by Aerostart.....
    Oh...I see...it was pumped full of liquid diesel, didn't start, then was made to fire by using Aerostart.

    Hi
    My observations of people using aerostart, in what ever crudely named tin, is they use too much. Lots too much. Certainly cracking pistons in diesels is common with using starting fluids, so I do believe dmccurtayne.
    SO BE WARNED !

    I haven't read all the previous posts but.. Could the 'water in fuel' sensor be doing it's job?
