Pulsar Immobilizer Problem

Sounds familiar. I've had similar issues with my Pulsar. Does the security light behave erratically? Have you tried any troubleshooting steps related to the key or ignition control?

The security light does flicker intermittently. Besides verifying the battery voltage, I haven't attempted any advanced troubleshooting. Were your symptoms identical, and did you pinpoint the key programming as the definite cause?

Yes, flickering security light and all. While I can't say key programming is definitely the problem without further diagnostics, it was for me. Best bet is to take it to a workshop and have them check the key and immobilizer. Save yourself the headache.

I took your advice and visited a workshop; re-programming the key resolved the problem entirely. Total cost was 45€. Your insight was invaluable.
