Things do fail. THe Bosch LH ECU is pretty robust and tolerant of much abuse even while testing. The exception is the '89 LH 2.4 unit which has a notoriously weak drive circuit for the fuel pump. If it IS an '89 AND it does not run, try jumpering the fuel pump relay. If it then runs, you have your culprit - the ECU. If you replace it, replace it with one from a '90 so that it will not recur.
