Have a Hyundai Sonata 2004. Car turn over but does not start. there is no spart in the coil. Replaced the Crankshaft position sensor and still not start. Need help!!

if there's no spark, check the battery for voltage, check high tension lead to coil, check resistance work on a scale of 23,000 ohms per meter. check the coil for resistance, you'll need specs for that, try the net. if the car cranks, but doesn't start, i would go through all the usual stuff, like plugs - check the gap and condition, h/t leads for wear and damage, check and or replace air and fuel filters. maybe check the operation of the fuel pump too. can you tell me why you replaced the crank sensor? have you had the ecu scanned ? if not maybe it would be a good idea.

timing belt? dies teh roer turn in the distributer when teh engine is cranked? if not then it is your timing belt you will need to get a head job if you broke your belt cheapest isnt best on machineshops ask dealer who they use save your self teh headake on head rework

I replaced the Crankshaft position sensor because few weeks ago I scanned the ECU and I got P0335 message. in the mean time I also replaced the camshaft sensor and the Coil because they were arcing. Now the car does not start and I can not figure out why. Is there any relay that ishould wory about? I checked all the fuse and they are fine
