Firstly, you should get a chimney-sweep in for two reasons...a) he will establish that the chimney is still open and functioning and b) he can clean it, given that you do not know whether it has been cleaned for years. If it hasn't it is a fire-hazard. I say these things, as I'm a bit concerned as to why you have failed to get it going.
Once you're sure re the points above, place crumpled up newspaper in the grate and top that off with kindling-sticks placed criss-cross, then pieces of coal on top of those. Light the paper in two or three places.
In the absence of paper and sticks, place two firelighters in the centre of the grate and smaller lumps of coal over and around them, with larger pieces at the back and sides. Then light the lighters.
When the fire is out afterwards, clear out the ash but save the cinders, which you should then use to cover over the coal in future fires. Good luck!
