I have a 92' buick centry i have a major problem with stalling
now i'm getting no spark can anyone help !!!!

Check if your getting injector pulse. If not then you may need a crank sensor or ignition module. It is hard to say for sure what it is. Might want to just try a new crank sensor first since it is cheaper than the ignition module. I didn't really want to reply to this post because there isn't enough info to tell you what could be wrong but all that it could be if your not getting spark is the crank sensor/wiring to it and connections, ignition module/ connections and wires fuse,and coils but I wouldn't think that all 3 coils would go bad at the same time.

crank sensor is cheaper to buy but a pain in the azz to change compare to ihe icm. just take off the ign control midule, most parts store will test them for free

sry didnt reailze this was a few mos old....hopefully u figured out ur prob by now
