The only problem with using something such as easy start or simliar, is that the engine will purely NOT start without it from then on. They coat the internals in a layer of carbon stronger than diesel ca take off that almost prevents the engine from running without a spray to start it if used frequently, and can only be lifted by a cleaner additive. I would do as suggested and jump it, if you dont have jump leads someone else near you most deffinatly will.
A diesel is harder to start if the battery is flat as said as the glow plugs need time to heat to start the reaction off that will fire the cylinders, and running unburnt diesel via bumping is bad for the cat too (again as said) its minimal but frequent use can really knacker them.
Just try Charging your battery before bumping, then if not, jump start and again if not get a new battery and glow glow plugs if its naff to start.
