Help 92 3.1 WONT START details inside!

OKay the other day , the lumina 92 with the 3.1 was driving and it started to jerk and chug and stuff, well then the check engine light came on and , i ran codes came up as 42 and 43 which are knock sensor and the ignition module. I bought the ignition module thinking it was it, Before it didnt run and we put the ignition module on and it ran for 2 min and the stoped, and now we cant start it back up. What could be wrong with it, we just put a new fuel filter on it. still nothing, we turn it over and it takes forever to get it to even want to pop or even make a attempt to start. what could it be? right now im out of ideas, maybe possible out of time ? POST PLEASE I NEED THE CAR TO WORK!

You try shooting it with ether to see if it'll fire on that? That'll at least tell you if you are dealing with a spark or fuel issue. Try wiggling the pigtail from the crank position sensor while someone cranks it, too.

where is the crank positioning sensor? ... we got the ignition control module error and replaced it with a new one but we are still getting the error? .. We also checked to see if the it was a fuel problem, it squirts gas so its not that, we checked the 3 front plugs for spark and they spark any ideas of what it could be?
