Go back to basics. Disconnect the enable wires and see if they come on.

Unless your 100% sure and confident that the schematic you have works it's always a good idea to wire in stages. Start with just powering up and seeing if latching system works and you have power to right places at the correct voltages.
Then start introducing things like enable or fault monitoring etc.

Ideally you should have written down all the I/O pin# your using and what's connected to those I/O #'s. Then when you have any trouble you can start tracing wires from that Pin# back to it's device. Makes trouble shooting so much easier.
