So the car under go a fuel and brake line overhauling from front to back everything new. It drove fine from the garage back home and now it doesn't have spark. I towed it back at the garage to figure it out and after two weeks being there my mechanic gave up. He redid the cps, it does get signal he said but it won't spark. I'm wondering if there is any plugs that he has connected wrong that are very similar that might effect the car getting spark. Please I need help.
