Depending on how much starting fluid used, I'd agree it should run for a second or two. It does sound electrical like there is not a proper spark. The circuit you changed for the auto park function also ties into the ignition at the ballast resistor on firewall. One thing you might do is verify that the voltage at the end of resistor with yellow and white wires is there and a constant 12v to ground as long as key is on. When starting, that is bypassed by solenoid but needs to be there after starter quits. If that end is OK, then would measure the other end of resistor. If still OK but maybe slightly less than 12v with starter off, then verify the rest of ignition and spark is good.
