Done a fresh build it started up to warm up.. But after i shut it down it wont start. All fuses and relays are good no power to the starter.. Changed the ignition switch three times. All lights come on dash ones too fuel pump kick on hard.. wont crank over no power to small starter wire.

 

I would think it's a starter or starter relay,most likely the starter,I put on a new starter once and took the old core back for refund and the thing let me down at the auto parts house,what luck.You can check it by running a screw driver across the two terminals on the starter if it turns over then it's the relay.
