I don't even know if this forum includes people with small Isuzu trucks!
I have a 2006 NPS 300 and desperately need a set of electrical diagrams to help me resolve issues with both the dual tank fuel feed system (which is regularly starving the engine of fuel) as well as the 4WD activation system. I'm happy to purchase, I just need to be guided in the right direction. Frankly, am happy to purchase an entire manual if available.
