1990 lexus LS400 (NO CRANK)

[Bodyswapped53chevy]

Hello everyone!   I have a 1990 ls400 that I cut in half, I welded a 1994 ls400 lengthened rear hald onto the 1990 front half.  I lengthed my unibody wheelbase to 115in to fit under my 1953 chevy 210 body.  It ran fantastic and drove pretty well until I parked it.  I went to start it and the cluster lights up but when you turn the key to start nothing happens.  I have tried a different starter, and swapped a relay to see if that was the issue.  I believe there is no power going to the starter relay location in the under hood fuse box, I heard there is an "ST" fuse near the kick panel that could have been the culprit all along.  Is this "ST" fuse on the part of the fuse block that has the turn signal relay behind it?  Thanks for any input in advance, if someone has a diagram showing the "ST" fuse that would be awesome.

UPDATE:  Was able to confirm the 7.5a fuse circled in the picture above is blown.  Changed fuse to a new one and still have no crank, believe there is still no power to the starter relay location under the hood.  (Tried to bridge the spades to manually jump the starter and got nothing.
