Have you double checked all electrical connections that you might have moved or unplugged to change it out? A loose connection could be causing your issues.


yes all connections are good . only disconnected headlights , fan . I pulled the rad support to get to the thermostat could I have screwed with an air bag or impact sensor? I have no manual for this car either which complicates the problem


Just for giggles I would try unhooking your battery for at least ten minutes. Sometimes resetting the system helps clear any code issues that might be present.


ya tried that still no spark. no diagnostic codes coming up on the reader. However I have an engine with a lightning bolt thru it and an ECP light on on the dash does that help?
