When you say good pressure-did you check it with a fuel pressure gauge and what was the reading?

Try this spray some carb cleaner into the throttle body and see whether if will start and die. If it does open up the IMTV and inspect the poppet valves and regulator.

i did that and it start and then dies

Investigate why you're not getting fuel start by checking the actual fuel pressure, then give me the readings. Furthermore, Do you hear the fuel pump come On for 2secs?
