Today I replaced the thermostat. It did refire, but still ran rough, then died?

My truck overheated last night. When it did, it went into protect mode shutting down some of the injectors as it is supposed to. Today I replaced the themosat. It did refire, but still ran rough, then died. I started thinking temp sensor, replace that and now it wont start at all. I seems like its not getting any fuel. I cant here the fuel pump.
Do you think its just cruel irony that the fuel died while trying to fix my overheating issue? Or, is something I dont know about need to be reset to restore fuel?

Thanks in advance for your help!
