where did you buy it? Autozone? try to buy one at Advance Auto parts or Oreilly's. Actually you need to have ground in order the coil to work properly. if there's no ground, it can be a short on the wire, and if there 's no short on the wire, then its the PCM.


Check for a trigger signal at the coil, unplug the coil and put a test light between the connections, crank engine then test light should flash, if it don't then the ignition module is suspect especially if it has never been changed. These rigs are pre OBD 2 are can be rather finiky with engine control systems diagnosis, if you are not familiar with this system I would recommend that you take to a shop you trust. Parts on these can get expensive very fast, so you don't what to just start replacing parts with the hope you find the problem.
