Please anyone! 90MM 2.4l ground spark question

[Lanklo]

Have ground to power transistor but no pulse. Can a bad coil (checks in spec) cause a no pulse signal at the transistor.
Have no spark and have checked 2 diagnosed good ecu.
Been frustrating for months
Thanks

Could the power transistor be bad? I know it is kind of common on 4g63's/DSM's. If not check all the grounds for the ECU/wiring.

New transistor and grounds all checked.
But thanks for the reply..
