I have 2004 G35 Coupe that won't start. No OB codes found on scanner. Sounds like it wants to start but it doesn't. Already changed the 2 cam sensors and fuel pump. Going to change the crank sensor today. Any other suggestions?

If the crank sensor does not get it, which I doubt since there are no codes, so what you need to do is a fuel pressure bleed down test. With the pressure gauge hooked up, cycle the key to build up pressure on the gage. With the key off, watch to see if the pressure drops more than 5 lbs in 3 min. If so then there is either leaky injectors, leaky spider lines, or leaky fuel regulator.
Borrow a noid light kit from autozone and see if the coils and injectors are getting current. If they are getting current it must be a compression or fuel pressure issue
Check that fuse that connects with the positive battery terminal, sometimes it goes out randomly recently happens to mine had it sitting for 2 weeks till I did that and boom everything came back on
