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-- use a gage and check proper fuel pressure. check fuel injector pulse. Any applicable trouble codes? Those are the basic checks, in my opinion. Let us know what your missing, spark--fuel--whatever.
