Went mtn. biking today in friends '00 Nissan Frontier (V6, 4x2, loaded). Gave a guy in a half ton Chevy a jump. When he hit his starter, my buddy's Nissan went dead. No pops or cracks or arcs from the jumper cables, just dead. Another passer-by stopped and jumped the Chevy, it ran for a mile and died. Did this once more and then ended up riding 27 miles back to my house for the Ram, on to Uhaul for a trailer, and now his truck is in my driveway. What about this Nissan? We checked every fuse we could find, disconnected the battery for about 15 minutes (hoping to clear any fault codes) and not a hint of anything. He had power to his lights and interior stuff when we left, when we got back the lights were dim and his power locks/windows were out (like a weak battery). Tried to pop the clutch before we left and it would sputter and not start. We'll take it to a dealership tomorrow and he'll get it fixed Monday if we can't come up with anything. He's been trying to find a Nissan technical reference / club / association / help-group ever since I joined the TDR and says there is no good info resource that he knows of. If anybody knows the fix or a place on the net to find the fix let me know. Thanks.
