I just bought a Nissan 350z HR engine and for some reason,when I engage the first gear the engine is not revving!If I put in neutral it works..And also my gauge clusters are dead!Can someone help me please?

 

Welcome- it might help if you post the year, mileage and condition of your Z to help with the guesses. Also, when did this problem first start? I assume not when you first bought it, but was there anything else that happened to this Z that caused this chain of problems?
