I acquired a '74 260Z, a few yrs. ago. Had to help my nephew with his "neighborhood committee".
It ran well enough to load/unload. I've cranked it over, often enough (lube in cyl's) to keep her from freezing up.
Time to do something with her.
Don't get any fire to plugs. Engine spins fine. Compression is 122 to 130. All connections checked/cleaned.
Fuses/fuse box checked/cleaned. Resistor wires seem to check OK. Safety switch gadgets ok or by-passed.
New coil, just in case.
I went through the process for 2 or 3 days. The only thing I observed. A couple times it wouldn't spin over/no sound.
I pushed re-set button, and she'd spin. No, I didn't make it spin over for too long; at a time. :(
I have a factory manual, but it doesn't have a troubleshooting section.
Sure would like to hear a "snort" like it's trying to start.
I'd appreciate any experienced advice.
