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!
