Ok,. Good, it sounds like there is continuity to ground.
Next step is to ohm the signal wires since we don't have a scope to see if they are getting signal from the ecm.
To do this, you will have to open the ecm case.
The ecm is in the firewall on the passenger side of the car.Unbolt it and pull it out, then open the case.
Here is a diagram of what the harness will look like when you unplug it from the ecm.
I have highlighted the pins that run the coils.
Coil #1 you want to check the brown wire and pin #62
Coil#2 is the Purple wire and pin #82
Coil #3 is the Blue/white wire and pin #61
and coil #4 is the gray/red wire and pin #80
same deal, we just need some resistance.
