Your symptom could mean that the ECU is shot. The injectors pulse by grounding through the ECU. Before replacing the ECU make sure that the two or three ground wires that attach to the cylinder head usually at a coolant hose flange stud/bolt are intact and in good shape. Sometimes the wires corrode and fall off or lose contact. A common issue is people forgetting to re-attach those wires after working on the head or engine.
Since you are reporting two of the four injectors as "bad," check the resistance of each injector and the continuity of the wiring. To test to see if the ECU is pulsing use an LED test light to check the pulsing of the feed from the ECU. Disconnect the injector harness at the injector buss connection, apply the LED test light leads across the contacts of the wire and have someone try to start the car. The test light should flicker. If you get no results reverse the test light leads and try again. FR
