Well my grandmother has a 1996 AWD blazer, and it wasn't running correct monday, so I popped the hood and noticed sparks jumping from the ignition coil when we hit the gas. I'm assuming this means it is bad and needs to be replaced, it now will not start but you can still see some sparks from the ignition coil. How hard is it to replace this and what kind of tools do you need? If it was nice out I would just try to do it, but its currently in the 30's and I dont have a garage to work in currently, so the shorter the time it takes the better. Any help is appreciated. Thanks Jon

 

It is quite easy. If you remove the whole bracket (2- 10mm fasteners), you will remove the whole ICM/Coil assembly. You can then take it someplace warm to swap the coil out.

 

Alright, Sounds simple enough......Thanks for the quick reply
