Well, I messed around with the button a little more today and found out that I wasn't waiting long enough for the flash to occur. Now what I'm having a problem doing is getting the system into test mode to check the duty cycle, as described on the landiss page.:

For California cars, starting in 1988: Press the push button switch on test connector X92 (passenger side, between the two firewalls) for two to four seconds. The LED will flash once, indicating no fault code is stored in the system. Now press the switch again for two to four seconds. The LED will be on continuously, and the injection control is switched over to an on/off ratio output.
As mentioned above, the LED flashes to indicate that no codes are stored (one flash) when I press the button the first time. On the second run, the LED doesn't stay on but instead flashes once again. The cycle continues and I'm unable to get into test mode.
