Good Day everyone this is my first time posting to this forum. I have a 2002 Suzuki Carry G13BB with a no spark issue, before completely failing only one coil pack was firing, wouldn't start then no spark at all. I've replaced Crank sensor and both ignition coils, still no spark, checked all wires running to the coils, crank and coil sensors there ok. Finally I changed the cam sensor then voila, spark but the engine still won't fire, just backfires. Then after about an hour or so of troubleshooting again no spark. Got another cam sensor and spark returns but it got dark so I left it till the next day. Next Day no spark. I'm stumped, could something be killing the cam sensors? Is it the Ecm? Any help is greatly appreciated.
I checked all the wires from the ECU to the Coils and Cam and Crank Sensors, they check ok for continuity. With key on I'm getting the 12v and the 5v for the cam, and getting power to the crank and coils. The trigger wires from the ecu to the coils check ok for continuity. I'm stumped, any other ideas?
No, I'm just going off the assumption that all was well before the no spark issue. My mind keeps going on timing, timing belt is ok, and I think it's unlikely that timing jumped but then again the engine not being timed correctly would still not create a no spark issue, Would it?
