@chinyoti i was going through this thread and exactly same issue is with my Baleno 2004 too. CEL blinks, car cranks and never starts. this has happened only 3 times in last 1 year. once i was stuck outside I.I Chundrigar at night and car simply refused to start. an electrician played with all fuses and relays and somehow after half hour effort the car started, he asked me to change fuses which i did the next day. 2 days back, the CEL again blinked but suddenly it got stable itself and car started. what is the exact solution - as you faced same issue in your same car too? please note i am using a copy key (programmed by himself with the scanner type thing) made by local chabi wala in Waterpump area and it works fully fine since 1.5 years.
