[Supras] Very Dead 1986 MA70 Supra - Need Help !

[Christian, Skip]

Group,
	I hope there is still someone left with knowledge on non turbo
MA70 Supras.  My 1986 1/2 is hard down - quit while driving a steady 60
MPH like the key was just turned off.  When cranked, computer shows a
code 12 (no Ne or G signal).  I have a parts car that was running when
parked 6 years ago.  I have swapped coil, igniter, distributor, and
computer.  I have verified the correct resistance values for all three
distributor pickups at the computer connector.  I have, also, checked
all fuses, circuit breakers, and fusible links that have anything to do
with the ignition.  I have no spark and nothing I have changed has made
any difference.  I did find one of the pickups in the original
distributor was bad.
	I really need to get this car running as it is my primary
commuter vehicle.
	Any suggestions ???   I am desperate......

Thanks, Skip
