EGR is clicking? Are you sure? The EGR on yours is vacuum operated, there are no electronics that go to it....unless you have a cali spec one...then all that goes to the EGR is a temp sensor...which shouldn't ever click.
If there is something under the left side of the dash that is clicking, then it is probably either the main or fuel pump relay. The ECMs are known to go bad in these....that would be my guess.....if it was operating fine before and you haven't did anything to make it not start.
