Make sure battery has a full charge and connections all good. If it cranks good but won't start, have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure, also check fuel injector pulse. Any applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader that will work with your vehicle. I can only help with testing.
