S13 won't start.. again

[Artigo]

93 240sx coupe, Redtop SR20 swapped about 2 years ago

When i turn the key relay clicks, dash dims, no crank or start. All power works in the cabin, fuel pump primes correctly.

-Starter was rebuilt in the last year
-New Alternator in the last 6 months
-New optima battery in the last 6 months, might go try to charge it again, but don't see why it would be bad.

Put on my new intake mani and exhaust mani last night and the car started twice after taking many attempts to turn the key it just fired up. This morning, nothing.

What am I missing?

Also the clutch switch is bypassed.

check your fuses and grounds? ground and relay on starter? I had a similar problem, i moved my batter ground from the tranny to the intake manifold,sanded the ground connector and the spot on the intake and it worked

check your starter relay.. next to passenger side fender. its a blue looking box with 2 connectors going into it.. i had a similar problem but mine was the lack of a relay.. just had a paperclip making the connection lol
