7m-gte no spark. Help please

[Drifter_85]

Ok got motor in and harness back on in the truck and i turned it over sprayed starter fluid and no go. Pulled out a spark plug grounded it and no spark. Don't know much about toyota's yet so don't know a good place to start is. Called it a night and decided to get some input for u guys. I couldn't find a good PDF so I have no idea which wires do what. Took off the igniter harness and three of the wires gave me 12v so with out any knowledge of this harness I gave up for the night

most likely check ur ground on the coil pack make sure the coils r grounded properly and if not check the signal to the coil pack ive had trouble with this wen i had my 7m. nd dont worry about it being the coils those shits r bullet proof

no more 7m for me tho 2j>all

Download the FSM then check the Ignitor with the procedure from it.
Also check all the wiring for the ignition harness and GROUNDS
