Does it turn over? if it's not turning over then it's not an immobilizer issue. The immobilizer on '98-00 cars kills fuel and/or spark, not the starter.
If it's not turning over you need to look at the starter fuse, relay, fusible link, battery terminals, ground wires, and the starter itself.

The continuous blinking after inserting your key means that the RFID signal from it is not recognized by the system. The transmission and the reception is done between the transponder and the key. The RF signal from the transponder reaches to the key and the key responds sending specially formatted bit streams. The transponder receives the streams and forward them to the ECU. Sometimes the communication between these are not well done when some unusual object is attached to the key or when you are at a location where very strong EMI (Electro Magnetic Interference) exists.
Is your key attached with something?
Is your location EMI free?
If not these, and the key itself is OK, then the transponder attached to the key cylinder, the ECU or the cable between them should be checked.
