Why would a 1994 Mercury Topaz have no spark even after the coil has been replaced?

Take out your Ignition Control Module (ICM for short). Take it to a parts store to have it tested. If it's good, check your cam and crank position sensors. Also, check the lead wire from the cap to the coil Also you can take out the distribuator and look at the gear on the bottom the gear is know to wear out after 100,000 miles on the vulcan engine 3.0. You can take out or disconect the SPOUT and see if the car starts. If it does change the computer. GL_ Good Luck.
