I have a 2003 infiniti g35 sedan with 269,144 miles and my car won't turn on ,it cranks but dosnt want to turn on ,sounds like something on the motor or under the motor that's keeping it from not turning on , yesterday last night It was shaking bad when I was going home ,I checked the oil and it has oil and coolant ,what else can it be?
Start with these steps, and let us know if they don't work/what you discover

Ok so turned it on an hour ago ,the only way I turned it on was because I pressed on the pedal while I turned the key on ,and it turned on so I took it to mechanic and they seen smoke coming from the back of the engine ,and said it was oil leaking on cover gasket,so they did a diagnostic and came out to be random mis fires , so they told me they can put a seal that I baught on the valve cover gasket for 250 ,I said well see if that's the problem ,because the motor was shaking alot when I left and when I'll pull up at red light the lights dim just a little like it wants to shut off when the motor is shaking so much,please find me a solution scotty!
If the lights are dimming, then the alternator is going out. Load test the battery and alternator. The other scenario for random misfire can be the the low fuel pressure, Pressure test it after you change the fuel filter.
I’m pretty sure your lights are dimming because of how low the idle is going from the misfire. Unplug one coil at a time to isolate specific cylinders if possible. Most likely you have coils that have failed
