All grounds there, car was running with the wiring before, some derp arc a ground when jumping and stopped work.
Soooo all relays and fuses good. Igniter wasnt showing correctly so put in MSD 6AL and still no spark.
Followed wiring but dont see how ECU can read IGF for return spark if only the IGT/Key power goes to MSD.

#10 and #20 are the wires that the ECU grounds internally to fire the injectors.
If you have power on those wires, check that the ECU grounds are good. Those
are the 3 or 4 brown wires that connect to a single brass ring terminal that is
clamped under a bolt on top of the inlet manifold (near the back of the engine).
Those grounds are easy to miss if you have had the engine wiring harness out.
