The truck runs and drives fine. Just won't start.

(1999 Chevrolet S10)
The truck has good fuel pressure and spark. It also has a new crank sensor and ignition module. If I spray starting fluid it starts right up. I can drive it on long trips (60 miles+) on the highway at 65/70mph with no hiccups. But it just won't start without a little help. Any idea what the deal is.

What is throttle position sensor reading at closed throttle? > What is coolant temperature 'sensor' reading on cold engine using scanner set to live data for these readings? IF you can provide that info.. Maybe we can help!
