Motor turns over but won't start plugs r dry when I take one out is that spark or gas problem

Possible that gas is not getting into the cylinders. Spray some starting fluid down or into the intake. If it rumbles to life for a second, if it even fires a bit, you know that it is not a spark problem, cause yes it's got plenty of spark-good ignition-, so it must been not getting gas. Or if no effect from the starting fluid-careful, it's highly volatile- then it could be a spark problem.
If it fires, you would start diagnosing the fuel circuits that apply. The fuel pump puts gas up to the engine, to the injectors and under high pressure so the injector will spray gas into the cylinder. It's that simple. You just have to trust the manufacturer did a good job on the mile or so of wiring it all together so the computer can make the engine run. Any time you have a problem, check for trouble codes.

You should hear the fuel pump in the gas tank turn on for 2 seconds, to put pressure in the fuel lines and up to the engine, when the key is turned to ON. Make sure you can hear it. You may need to stand near the rear of the car to listen for it while someone turns the key to on. If you don't hear it, and the car won't start, you would need to check the fuel pump.
