Hi I have recently bought a 280z 1977 year. I have been through the car sorting it out. I have been having 2 problems which I was hoping someone here could help me with. Firstly the car would turn off all of a sudden whilst driving. I found an issue with the wires that go to the coil and so replaced some of the wires and connectors. However the car is still turning off from time to time but restarts again immediately when this occurs. I wonder if I need a new coil or is it worth changing every wire and connector. The second problem seems to be a fuelling problem if I am not mistaken. The car is driving along fine then all of a sudden its starts juddering or the accelerator does not do anything at all as if there is no fuel going to the engine. Then all of a sudden the car picks up again and drives well and then after a short while it stats juddering again. Does this sound like a fuelling issue? Would I need a new fuel pump of does it sound electrical? I have given the car a full service and changed the plugs and fuel filter etc. Grateful for any advice.
