First thing scan for codes, Will it start and run on supplemental fuel? Use carb cleaner, starting fluid, brake cleaner and mist some into the intake and have someone crank it, If it fires up diagnose the fuel system. I can not emphasize enough on these modern cars always scan for codes, even if u don't see any lights on the dash. I had a tech **** around on a job for over an hour and I ask him if he scanned for codes, He said no, then he did and holy crap there's a code stored which sent him in the right direction. I see to many people on here trying to fix there own cars and that's great but they list a crap load of parts that they replaced and its still not fixed, wasted money. People try to save money but they end up costing themselves way more in the long run.
