91 chevy Blazer would rire up drive about 1/2 mile then die, so I added a cleaner this got us home. Then replaced the inline fuel filter it got worse. It would fire up run then die then refuse to start, after a while it would start run then die again. I relaced the cap and roter but nothing I then replaced the fuel pump, filter cleaned the lines, cleaned the tank, replaced all the o-rings and gaskets and rebuilt the injectors, nothing. checked the injectors then replaced them, nothing, then I ran the codes and it gave me a 12 that says it the control module that needs to be replaced. The only problem is that ther are 4 typed of control modules on a vehicle, so the internet states. so would it be the electronic spark control module? If not than which one?

 

you should change the ignition module and the wires.had the same problem on my car
