Keep in mind, you can still have good voltage at the starter with a bad connection. The problem will be when trying to pull the large current through the lines.

And I believe the Supra's have a starter relay, that may be what is clicking.

okay, i did have that in mind and a helpful mechanic that i know dropped by and help test things........ as a point of curiousity he asked if i had an alarm system........... well i do, aftermarket, and what is happening is exactly what it did before when i sat inside and armed it. problem is it won't disarm. How it got armed i do not know. The car is in a spot where there is no need for me to use it, so i just never thought about it.
the alarm i believe is overiding the start function, so no matter how many wires i pull and clean it will be the same. Well gonna drop down where i had it installed and see if they can tell me how to override so i can at least eliminate it. keep u posted, least that way if it is the problem some other poor smuck won't go what i went thru.

thank you. finally got it running. Was the simplest thing to do.
I went thru the tsrm list of possibilities, starter/ leads/battery/ relay and it was on the final one that i hit on it.
Was the nuetral switch. And even then the switch wasn't faulty.
I was about to pull it till i saw how buried it ws behind the exhaust, so i thought first i would clean the connections............. a shot of gunk, folled by a shot of brake cleaner and a liberal shot of elec contact cleaner. wipe it down. then when tried to start, it started when i held the key and went thru the shifter. Kicked over on my way back into nuetral. Has been good since.
I assume the connections were corroded.
thks again.
