aristo in sc300 problem
 

i have a sc300 with 2jzgte auto when i tried to start car (first start) the starter made a click noise and then smoke came from starter or wire not sure so now my problem is that the starter relay is acting funny when i touch the contact in the starter relay the engine turns and while engine is turning i take out starter relay and engine still turns with no key in ignition i have to disconnect battery to stop it.When i use key all lights in cluster and everything inside works but no turn over of engine like no power is going to it.I check every fuse in and out car and all r good i used another starter relay that works from another sc and nothing. NEED HELP

You probably need to replace the starter itself. Its probably shorted on there somehow and keeps turning the solenoid or something. Take the starter at a local store and get it tested. Its free. Then go from there.

Sounds like a wiring problem, when my sc smoked it was because of a bad alternator.
