First try a different battery or a jump start to see what happens. The battery may still be too weak to power stuff.
This thread on the RX forum is sort of similar and may be of some help with diagnostics

[QUOTE=LjeksesES;11013394]Is there a light on the start/stop button?
no power to push start also no power to dash... lights inside comes on door will unluck and lock the car trunk and horn works headlights coming on just no power to dash or the start button

Thanks to everyone that posted a comment I got power back to dash and strat button I took the dash out I found the ecu I'd code its behind the heat and ac very hard to get to even with the dash out I got one from the junkyard and installed it also there some kinda circuit fuse is under the dash behind the cluster it was burned I think I might of did that with the tester given power to some wires and relays now my problem is no crank no start I got locksmith Came and tried to program it the key unluck and lock the car but no crank no start scuriry light flushing he did a some kind of flash or programming that take 16 minutes he tried 2 times no luck Also we did the obd connector pins for 30 minutes I try 2 times all lights flash in dash for 30 minutes still no crank no start I know push buttons good starter is good all relays and fusible link and fuses good I think I might need to get a new ecu I'd box and a new key and see if its going to work but any advice still welcome hopefully this Will help others in future

please help if anyone knows got this lexus stuck in my shop, 08 gs350, was testing vehicle after ecu replacement, recoded vin and align the sytem, got key working and all looked great, i tested the igntion on and off a few times and on the 3rd time i turned it off, after that no response like cluster went ghost, no messages on dash , just door light when opened, all fuses were clean and tested, relays checked too, battery is fully charged at supply 14.5v no comm ecu, no igntion, seats move only, interior light work, hazard lights work, headlight work, when switched to parking, only backlight light up for nav buttons and trunk/gas illuminate green. green light on switch turns on only if i switch lights on. the cluster does not light up at all, i can send power to ignition fuse 10amp first one in row and lights up the dash with tester power applied. everything was working just fine. felt like last time i turned ignition off, steering retracted back and flet like it didnt go all the way in and just shut down. after that i got no response , i was able to scan the immobilizer and found no errors there, showed key in the sytem, but i cant access pcm. brake lights also work. really got me stumped, also replace the ignitio starter switch, car just hit 100k miles.
