2004 Chrysler 300

2004 300M timing belt went. Replaced by shop. Engine turns over without interference but not firing. Don't know if there is spark. Have not received car yet. Shop that specializes in rebuilding engines says probably no damage to engine or heads. Something else. Any thoughts?

Could be the valve timing, spark and fuel problem

**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.
