have a 77 280z and i have changed ignition coil the pickup coil and it still wont fire
Check the distributor,if you have 12 volt,s at the coil.If no fire at coil,check fuse,s,if fuse,s are good,then it may be bad igntion switch.
All the glass fuse are good it has a new ignition
The only other thing would be distributor bad,have you checked the coil,and seen 12 volts, at it?Or coil is not receiving fire?If it doe,s not have 12 volt,s at the coil with igintion on,there is a bad relay,or wire bad going to it,if you do see fire at the coil ,,it will be the distributor.

These cars are known for connection issues in the wiring harnesses. Over time corrosion builds up in them. Check all the harnesses. Start with the ones on drivers side of car. Specially the ones right around the front intake area going to dist. also the ones on the front drivers side fender. Most times just un hooking them and adding a little grease to the prongs will get them back firing.
Also make sure that you have a good negative battery cable connection on the frame and motor. This will also cause a no fire issue with these cars.
