I change the crank shaft sensor and the coil pack change it also I checked the fuses and all are good and still have no spark what should I do

. Check all under hood and under dash fuses with a test light or multimeter. Visual inspection is really not good enough. You want to check for power through the fuse.

. Check for codes.

. Clean the main PCM ground.

. Check the ignition switch for wear or pitting.
