Hello and welcome to JustAnswer!There are quite a few things that will cause a lack of spark. You could have an issue with the powertrain control module, it may be a wiring issue or the ASD relay, and it's very possible that one or more of the parts replaced are still causing at least part of the issue. Aftermarket electrical parts will often cause issues.The first step in diagnosing the problem is to check for fault codes. Any issue causing a loss of spark will set a fault code and that will give a starting point for diagnosis. Do you know what codes are setting?
