if your saying it cranks good, but, won't start, check the basics. Make sure battery has a full charge and connections all good. Have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure. Check fuel injector pulse. Check for applicable trouble codes. Those are the basic checks, in my opinion. At the moment, I don't know what the heater has to do with it?
