If your start while testing was from cold and it only ran for 1 minute or
less, at idle speed, and now it wont start, its almost guarenteed to be
flooded. Very common on the 5 and 6 cylinders when treated like this.
Leave it sit over night, then attack it with a wide open throttle and a long
burst of cranking until it is self sustaining then hold it at 3000rpm or so
til it runs smoothly, let it warm up properly before shutting off this time.
