Default Same problem here.

I have a 2003 Dodge Ram with a 5.7 Hemi. the other day i was driving and it started to tremble and finally it stalled. Now when I try to start it sputters and and stalls. I was thinking maybe my Fuel Pump , what do you guys think?

Could be, but there are easier things to do first: Plugs, throttle body, air filter, PCV valve. A dose of Sea Foam might help, too. Do you run it down to fumes a lot?

Not really, I recently changed the plugs but could'nt get to the last four due to the master cylinder. I have an o2 code and and a evap code as well.

Neither of those points to the fuel pump. Heat is its biggest enemy. An evap issue or O2 issue could make it run bad, I would suspect.

I would start with the 4 overdue plugs.

It probably doesn't help that there is no muffler , catalatyc converter still on it though with straight pipe.

Default fuel filter

my 2004 has a non serviceable FUEL filter. I think the 03 is the same way.

Do a compression check. I had the same sounding problem last year. It ended up being a broken valve spring.
