Truck cranks but no spark. Igniter/ingition module has been replaced. So has crank angle sensor, Dist. Cap and rotor and coil checked out good. Computer is not giving any codes or responding what so ever to an Obd II code checker. Could it be the distributor or possibly the ECM? Feelin kinda stumped right now. Thanks a lot, CJF

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