Komatsu FG25N:
No spark

I have a 2006 komatsu forklift, k21 engine will not start ,no spark 12 volt pos at all 4 coil packs, reading rpm through obd2, I went through the wire harness to the ecu all wires tested good to all sensors getting one code and it is for the speed sensor, I don't believe the speed sensor will keep it from getting spark.
The ecu has been replaced. All fuses are good.
