I finally put the car back together after about 9 months of work. Unfortunatly the car wont run , but it does turn over fine. At first we thought it was the timing, but we checked and everything is right on top dead center. The car is getting spark, gas, combustion, and the timing seems to be right on. Why is it doing this? BTW the car is a 75 280z and on the thermostat housing there is a small ground plug that has a broken wire, it used to have one ground and the other "terminal" was already broken off so I dont know what it looks like. The car ran before the disassembly so I dont if it is too important, but since something similar costs nearly $80 at the parts store, it must be important any replies would be greatly appreciated, I wanna get this thing on the road!
