Does the Check Engine light come on for two seconds when the key is first
turned to "II", then go off again?

Any codes stored in the ECU?

Did you reconnect the ECU ground at the thermostat?

At the bottom injector, find out which of the two wires is "hot" with the
key at "II" (the other one is grounded by the ECU when it wants the
injector to turn on). Remove the connector, and carefully hook up a
temporary connection from the hot wire to the hot side of the injector,
then ground the other side of the injector to the block or some body
ground. Does the injector now spray fuel?
