Make sure you have all the positive and negative leads attached to the battery. Once before I had problems with starting and it was from a loose positive lead. I've also had an ecu go out and that caused no start as well. Usually if all things are fine I'd check that. If you have a fuel pump rewire check to see if you attached it back on.
