Wiring the fuel pump to the ignition switch is a bad idea. The pump draws too much current for the switch contacts. That is why the relay is there. Plus, the ignition switches are somewhat weak in these cars to start with.
Most likely you don't have enough fuel pressure for whatever reason: bad pump or too much resistance in the electrical feed to the pump. You could have a bad ignition switch at this point as well.
I'd reset the codes and see which ones come back. They could be old at this point.
