Fried ECM???

okay so 3 months ago my car was dragging butt real bad, hesitating in first and second gear and dying in rainstorms. I thought it might be the fuel filter and so in trying to change that, i pulled the inj 1 and inj 2 fuses because at the time i couldn't find the fuel pump switch. After that, my car would sit there and crank, but would not turn over. After a month of scratching my head i tried one last time and it started up, but ran like hell. The idle is horrible and every time i barely touch the gas pedal it redlines. It threw me a code 33 (MAF) so i changed the sensor and nothing happened. i also changed the o2 as well. i have spark, air, and fuel (43 psi) , but no engine running. did i fry my ecm or is something else majorly wrong?

One way to tell

get one from a junkyard and slam it in, lol. Mine did a minor crp out on me, was on the 02 sensor circut. I got a good one for 35 bux or so.

you could probably find a ecm in the junk yard for cheap, yards here have alot of 2.8's in them.

Not to sound stupid, but clear out ecm by battery disconnection. Run car through some driving cycles and then use the perfect paper clip to check for codes.
