It sounds like you did miss a ground somewhere. If you modified your own harness, then I would just double check everything. You would have had to add the ground for the fuel pump relay, usually by tying it into the grounds already in the harness, but if you didn't do that, then you will need to add one, just make sure its a good ground! As for the no start, could also be the same problem if you did in fact hook the fuel pump relay ground into the grounds in the harness, but missed hooking the ground up when you installed the harness on the engine. There are usually three grounds, one at the back of each head, and one down low behind the power steering pump, miss that one and it won't start, seen that happen a lot.
