You don't magically fix anything by removing a battery cable but you have introduced more problems. The Engine Computer turns on the automatic shutdown relay. If it doesn't do that on its own during engine cranking the engine isn't going to run anyway.
With no punctuation in that huge sentence it can be read at least three different ways. By "no power to the relay", do you mean the relay is not turning on or there is no 12 volts there to be switched on and off? You should find 12 volts on one of the terminals in the socket all the time. If it is missing check the fuses in the under-hood fuse box.
If you do find 12 volts on one terminal, feel that relay while a helper turns the ignition switch on to tell if it's clicking on. It should turn on for one second after the ignition switch is turned on, then again during engine cranking.
Please consider a to help us answer more questions.
