What is an 'icms'?

When you replace the cylinder head, did you make sure to use all original bolts, re-connect the ground strap to the cab, etc? If you had bolts left over... not good. If you didn't hae enough bolts to hold down the coils, not good. I understand the coils use all fasteners to ground the coils, so they all must be replaced if removed or new coil installed.
If you have no spark, check that your coils are functional. If you have the 8-plug, swap one coil for another.
