 Where's coolant temp? Where's intake air temp? What does mass airflow sensor reading say? All right. This is Hawaii. Lots of bugs. I would try unplugging the mass airflow sensor and seeing if the car starts. I've seen things crawl up in there and spiders build webs and all sorts of ugly things and cause this exact same scenario. If the vehicle runs without the mass airflow sensor connected, or more importantly, there's a 4.7 liter V8.
