Question type: Maintenance & Repair

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.
