Answers :

If you had a shorted ignition coil, it may have damaged the ignition module.Take a coil pack from another spot,plug it in just be sure your new one is good.if it still won't spark replace the module.I've seen these that won't spark cold but run ok hot.You can try to heat the module with a hair drier to see if you get it to work,but even if it does you still need a module...good luck
