Where in North Carolina? did you check the distributer cap? wires? plugs? coil pack if you have one? if you leave near Hendersonville There is a shop called Smith Family Tire there not supra experts but the owner i think has 2 turbo supras he works on and drives ones white and ones red One has some mods done to it and the other doesnt that might be the best place to go if you live near Hendersonville or Asheville.

Just making sure...the previous advisor suggested you might have a distributor, plug wires, or only one coil pack. Your TT has six coilpacks, no distributor and no plug wires.

Have you checked the continuity in the harness between the ecu and the ignitor, for the one lead you're not getting a spark on?

The TSRM has detailed troubleshooting steps...do you have one that you can refer to?
