one step closer! Sounds like the backfiring and dying thing may be because the TPS is not dialed in.
When the his pump went out I am going to take my fuel pressure gauge home from work today and test it

Sounds like you got a game plan. The TPS can be tested through crusiers tips also if that doesnt work.
