coil runs fine on another vehicle, it did run for a few minuates after i replaced fuel pump but it ran rough that was after new coil and icm but befor wires cap and rotor then i changed wires and it ran again for a min and died so i took off cap and inspected and it showed signes of excessive wear so changed cap and rotor. then looked at the crank sensor and wiring and found the wire poorly spliced together so i fixed it up and put new sensor in i dont get any spark from coil.

Have you thought of the pcm? That could be a cause of no spark even after all those shiny new parts.
