Fuses and relays are a good start, checking the fuses is easy with a visual, relays a lil harder to check if still ok go with a youtube video to test them,
If however still at a lost then it could also be a failure in in the wiring itself alot harder to check. and can be a break in the wire without the sheathe broken needing a test of the wires itself with a multimeter, thats if its a wiring problem

describe what happens when you turn the key to start up:
turns over but wont start, no turn over at all, are your accessories working in on mode, when turning the key to start,
try putting a temp light circuit to light up when you turn to start and see if its not the ignition switch itself

I have pulled ignition switch out and tested for power, nothing turning switch does nothing. Fuse in foot well are all fine left aide of fuse box has no power right side does.

I think the supply may come through the key switch to the Fuse box, (I could be wrong). This would suggest that your wire to the switch is open circuited somewhere, ie before it gets to the key.

If similar to 510,
This may help

Fuseable link?

[C.Randall]

Would HT lead stop any power getting to ignition? Not completing circut?

yeah check ur fuseable link it looks jus like a normal wire and u can not c that its blown you will need to test it the fuse link is a short peice off wire with a plug on each end aprox eighty mm in length

it is normaly kept by the + battery terminal or close to the fuse box like 510s and i think in some cases with datsuns from the factory they tied a spare link up by the fuse box

if you need to replace ur fuse link you can get a replacement peice from auto electricans
