2005 Xterra 105,000 4x4

question 1:
While im driving at any cruising speed the truck would run fine, the second there was any incline it would sputter/shake. Now it does it at any cruising speed regardless if the street is inclined or level.

Question 2: After the check engine light came on from what I thought was a result of question 1, I took it in and they said a catylitic converter was bad so I paid to have it replaced. Now my cruise control does not work. And it still sputter/shakes constantly when cruising.

(MOST IMPORTANT)question 3:
I woke up, drove my truck to work, parked it and when I was leaving got in turned the key, battery turned on. Radio, lights, power windows everything. Turned the key and nothing. No sound no anything. Got a jump from a buddy, still nothing. Switched out the battery from another nissan Xterra. Still nothing. Im fricken lost on this. Called the dealership and asked if it could be the anti theft system locked me out and they said that it would still turn over if that was the case and they have no idea either. Please help.

For question 3 check the 3 things I have in arrowsthey are fusible links and can burn up causing your problem. Also check the relay. I am assuming this is an automatic. For ques2 check your fuel pressure it should be 51 psi at idle or close to it with the key on. If you get it to turn over and start then check it.

When ever you run an Xterra hot it will set a code(turn on the check engine light) I can't remember the exact P#### but it will be defined as coolant temp overheating or something to that effect. Take it somewhere and have them hook up a scanner and pull the codes. If that is the only code then you can erase the codes to turn off the check engine light. If there are other codes then even if you erase them the light will come back on as the other codes set as you drive it. Make the necessary repairs to correct the other codes, once that is don't the mechanic should erase them before he/she goes on the test drive. If the light stays out then it is fixed if it comes back on the mechanic goofed up somewhere or all the problems causing the code to set wasn't fixed at that time. Anyway just erase the codes and that should do it.

We have a 2005 Xterra that the transfer case went out on. Replaced it with a used unit, and it wouldn't shift into 4wd due to low voltage at the shift motor. Replaced the motor and the electronics and it still has low voltage. We are assuming the issue has been there and that the unit probably didn't shift out of 4wd at some point and caused the transfer case failure. Even Nissan Dealer couldn't find a solution.

Have you ever heard of this?

The only thing you can do is trace the wiring back to see where the power is lost. Actually, start at the switch to see if it is bad. I have seen weak switches that can no longer handle the voltage and break down when put under a load.
