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.

Check primary and secondary coil resistance using a resistance meter. Verify there is power to the coil's BATT terminal and the distributor. Rotate the engine and verify the rotor under the cap is turning. Verify that the ignition fuses are intact.
