I have power in all the wires at the ignition switch

i was driving the truck and it just stalled, it is getting gas no spark changed pickup coil ignition coil and ignition module also changed cap and rotor still no spark i have power in all the wires at the ignition switch no check engine light the only thing Ive noticed is the gas gauge was acting funny bouncing and the brake pedal does not have to be pushed in order to take the truck out of park it turns over only in park or neutral but no spark
