Whenever the boiler goes to light it blows the E2 fuse - Any ideas as I do not have the light up sequence and it blows almost immediately.

or alternatively use a multimeter

one possible cause is that you have a problem with the main gas valve.. or a short on the cables to gas valve. best way to check is to disconnect cables to valve usually two push on spade connectors.. first isolate the boiler of all electrical supply. making sure that all cables are safe and not touching any boiler parts turn supply back on.try to relight. it wont but if fuse doesnt blow that is problem. another possible cause is if it has electronic ignition you have a problem with your high tension ignition coil. apply same procedure as above.
