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 visually check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure and check fuel injector pulse. Also, check applicable trouble codes. Those are the basic checks, in my opinion. If you have already checked all that, fuel--spark--compression--timing.
