Cranks but no start condition: Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. 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.

You have a timing chain in this vehicle. It would make a metalic sound if broken and most likely cause the engine to freeze up because it would drop against the crank pulley and get tangled.
A fuse wouldn't cause the noise. Is the noise coming from under the hood? Have you checked to see if there is spark and fuel to the engine? How many miles are on the vehicle?
