1uz conversion - no spark

[Oranges]

Gday guys, got the motor to crank and injectors are pulsing away fine, there is power going to the ignitor. Ignitors grounded properly, motor is earthed properly.

Everything seems to be right but I'm not getting any spark. I understand that spark is mechanical on these motors, so if it's cranking fine, what would prevent spark?

Any ideas?

What do you mean spark is mechanical? It's all controlled by the computer.

Where did you check for spark? Cyl or Coil? (Check coil if you haven't already, to rule out distributor/rotor issues)

Check the crank and both cam sensors

Check wiring to igniters from ecu, check wiring from igniters to coils. (make sure the wires aren't shorted to ground as well)

This is a little embarrassing but, at least I've figured it out!
I just haven't got the igniter modules plugged in!
I in fact, don't even have them but I'm working on that. When I get em I will plug em in, and hopefully she'll be a go'er

oops - but at least you found the problem
there is two ignitiors bt i think there is also two different types of ignitors
might pay to check

done something similar though
hooking up the ecu to power from the key but not when the key is in the start position
tooks hours to find

Does not compute...

hahaha I misunderstood.
I'm not sure exactly what they are, but there are two black things, that feed power to the dizzy. (the coils?) I mistook these for the igniters.
The igniters I don't have are mounted to the body near the battery (I think, I've never seen one first hand).

Igniter looks like this and has "igniter" written on it .1UZ has 2

This looks like one for a Supra not for 1UZ
