2001 Toyota 4Runner

The 4Runner started to miss and run poorly so I changed the plugs which I have done on 2 previous occations, but when I tried to start it it would act like it wanted to but never would. I checked the coils and and connectors, the front coil has no voltage from the connector I rotated the coils out just to make sure it wasnt the coil and even bought 3 new coils just to make sure it wasnt a problem with the old coils but there is still no power to the connector. I used a Multi Meter to check the ground and it is fine. I checked the wires going to the connector for cuts or nicks but everything looks good and is still in the factory wiring protector but I still have no voltage. Is there a sensor that would cause the voltage to appear on the other 2 coils but not the front coil or is there something I forgot to check.
