CRANKSHAFT POSITION SENSOR (CKP SENSOR)
The crankshaft position sensor, consisted of a magnet and coil, is located next to flywheel The voltage signal from this crankshaft position sensor is relayed to the ECM to indicate engine RPM and the position of the crankshaft.

What is the issue? Are there codes?

I have never heard of failure of these after 100k.

Ok, lets start with basics. Compression, fuel pressure and spark.

We know it has no spark so start with a compression test to see if the timing belt is working.
