My Sister Has This intrepid and A While ago it started to over heat. So i Replaced the water pump and thermostat on it. And now it has no spark. Everyone was telling me that i messed up the timing when replacing the pump but i didnt move the cams or anything i made sure everything went back together correctly nothing moved or spun. And if it was the timing i would still get spark. It ran before just would over heat. Any tips or ideas on what to check would be great. Also how can i check the timing where are the marks and everything so i can make sure. I dont have a manual on it either.
