Car is automatic with 110,000 miles and a p0304 code. Nephew said one day car started running really rough and when checked p0304 code but not sure when code actually popped. I changed coil and plug in 4 cylinder still crank but no start. Had a "mechanic" come look at it and "timing chain had skipped." Is it possible to diagnose skipped chain by just turning key bc sounds like normal crank, and if not what ways could I diagnose a skipped chain. Thanks for any help, Chris.
what ways could I diagnose a skipped chain.
You would need to check the timing marks on the crank and cam positioning to see if they line up correctly. The shop manual for your car can be found here:

Since you have a code there may be freeze frame data, have you looked for that? Also see the troubleshooting section of the site FAQ.
