I have a 97 Lincoln Towncar. 4.6 engine. I installed a rear coil spring and shock kit from Strutmasters. I disconnected the battery first then did the modification. When i finished i reconnected the battery and the car turns over but will not start. I have no spark. It drove in fine,sat a few days in the garage but I really didnt do anything to the electrical system. I am leaning toward the crank position sensor but was wondering if the PCM could have lost all its memory or something.. I tried to pull a code on it with my el-cheapo Autoxray code reader but it says no communication. Any thoughts?
