cavilier wont start what could this be?

I havea 01 cavilier it had been runnin rough when u first crank it up
and if u mashed the gas fast it would bogg down but going down the
road was fine i was driving it down the road and it just shut off so i
pulled over put it in park and cranked it right up went like 25 ft and
stalled 4 good i put 2 new coilers and a fuel filter my bf said the
coilers arent gettin fire we dumpt some gas in the throttle body and
nothing he tried 2bjump the coil omost started maybe even
backfired hes in the prosess of getting crank sensor out he said it
broke maybe thats all it is any help would be great
