What is your question?
Took it home and I started looking up anything that could be wrong with the car. I found that the crankshaft sensor was a big candidate so I hanged that. It was a pain but got it. Hopefully that would start the car it didn't. So on to the next step. Next I replaced the fuel pump making sure that wasn't a huge problem and it wasn't. After some further brainstorming I decided to change the spark plugs and the coil pack and my god did it need it. I thought I had solved the problem but another fail. I'm running out of ideas does anyone know what the problem can be.
How long has your 2004 Hyundai Sonata had this problem?
I’ve had the car for a couple of months now but it just out of the blue one day.

It has compression and spark my stepdad and I think it is a fuel problem we were thinking of changing the purge valve
