Hello together. I have a strange problem with my Suzuki Grand Vitara 1.6L 69kW (SQ416). If I engage 4WD (4H or 4L) while the engine is not running, I can hear the pump work for ~2sec and then go off, then after firing the engine up, Im in 4WD and everything works like it should. This is not the case when the engine is running and I engage 4WD - the pump doesn't go on.. But when I start to drive while in 4H or 4L the 4WD light comes on and starts to blink when I rev the engine up.

I have done my research on "troubleshooting the pump" (Google and other forums) but I couldn't find the same symptoms Im having with my Suzu.. I would be thankful if someone could give me a direction - I assume the problem could be electrical..

Thanks.
