Question about 1990 Lexus LS 400
I can only get the car to start by removing both the efi and starting relays and applying 12 volts to the correct terminal. ignition switch tested good. could this be a fusible link/open ground? where on the car can i find those? could it be a main relay? where is that located? does the 1990 ls400 have an immobilizer?

First unhook the battery for about a half hour to reset the computer.
does that have anti-theft on it.
a remote starter ?
second either swap the relays for the starter and fuel pump or replace them outright.
when you bypass the relay to get it to crank... will it start ?
if that radio is of the anti-theft variety make sure you know the code and how to enter it

I think gas is not getting to your fuel rail.
Could be the fuel pump. To access it you will have to remove you rear seat and take off an oval shaped plate. There you can remove it and replace the pump.

sounds like there is no power to the EFI relay, there is an EFI fuse in the under hood fuse/relay box, if fuse is ok take a power probe ( by the way there are 3 EFI fuses a 15 amp and 2, 7.5 amp ) remove the EFI relay and power up terminal #3 and see if the fuel pump powers up with the key on, this is the power circuit for the coil. injectors, and fuel pump.
check this out and let me know what you find.
