Starts like ass, sputters and runs rich

[TsiEagleTalon92]

I have had my Eclipse GS N/A sitting for over a year and a half and finally got it running again. It takes a few too many cranks to get it started, but when it does run it sputters while driving and when I get close to 4000rpms then it really sputters and sometimes cant make it over that. When it is cold you are not able to get it over 4000.

My thought is that my fuel pressure regulator is bad and is either not letting fuel return to the tank and is getting shot through the injectors in turn making it run rich and starting like crap.

Any thoughts as to what might be the problem?

did you put fresh gas in it?

Fresh spark plugs and wires?

[TsiEagleTalon92]

Fresh fuel with sea foam, iso heat.
New plugs, wires, Recharged filter. fuel filter was replaced before it broke.

Timing/timing belt correct?

[TsiEagleTalon92]

yup everything is in order the timing belt has about 20000 on it if that.

I think my MPI relay is bad, my pump doesn't receive power so I have it hardwired like my talon and that thing starts just fine.

before I started doing any real work on the car it started just fine but when I dug into all the things I needed to do to it it just stopped starting correctly.

O2 Sensor?

swapped it with another spare I have with no change so I swapped back.
