My 5.8 just quit on me the other night. I changed the ICM with a known working one as that was everyones first suggestion. Still no spark. I put a known good coil on, and the truck started, ran for about 5 mins than died again, again it is not giving any spark. Anyone have any ideas ????

Thanks

 

maybe the module u changed is bad also??? Or the coil. U can check a coil with a dvm,and u can have both modules checked at a autoparts store. At least if u have them checked and both test good, u know its the coil, or sumthing else, like pickup coil in distribotor
