1990 Buick Limited • 6 cylinder 2WD • 153 miles

My 1990 buick 3.1L, 153K, ENGINE DIED WHEN WARM, got towed home, cooled off started up, replaced fuel pump and filter, started up ran for 15 minutes, died - no spark to any plugs, checked icm, coils-OK, replaced CAS, ECM, checked all connections and voltages--OK but no spark? Any ideas

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
