I recently bought a 2000 durango that does not run, 5.9L, auto, 4wd, 113k miles. I put brand new terminals and battery in it due to they looked bad when i got it, it cranks over good and smooth, it has proper fuel pressure at the rail, and it has spark. It will start and run off starting fluid and run as long as you spray but dies as soon as you stop spraying...It has no codes due to the fact of sitting for probably around a year with no battery.
any ideas on what to do next would be great...

 

Could be way out there but it sounds like either a injector issue or a PCM issue...
