I have jumper cables from the neg terminal to two different points on the chassis and the motor so it is not a ground.
Only thing I have not tried is testing the ignition switch itself???

I dont have the manual, but ordered one as we are all aware they are not readily available anywhere.
No, that's not what I meant. When I said "ignition signals coming out of the distributor cap", I did not mean checking the constant signals out of the coil. In other words, I want to find out if your plug wires are bad - if your coil is working, perhaps the signal is not getting from the distributor cap to the spark plug?

Oh, and the TSRM Engine manual actually is available 'everywhere', since most towns have a Toyota dealership. Here are the part numbers for your car:

1993.5
00400-RM343-U1 VOL 1 REPAIR (Engine)
00400-RM343-U2 VOL 2 REPAIR (Chassis)
00400-RM347 ATM OVERHAUL
00400-WD174 COLOR WIRE DIAGRAMS
00400-14500 OWNERS MANUEL

1994
00400-RM359-U1 VOL 1 REPAIR (Engine)
00400-RM359-U2 VOL 2 REPAIR (Chassis)
00400-RM391 ATM OVERHAUL
00400-WD182 COLOR WIRE DIAGRAMS
00400-14507 OWNERS MANUEL

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
