    92 grand prix

    i have a 92 pontiac grand prix with 3.1 that does not start. i have spark and pulse only part of the time and when i do it will change timing. it seams like the ref. voltage is changing and it will come and go. when i have ref. volts it tries to start but then it sounds like some one turn the dist. and timing is off and then the ref. voltage goes away. has had two crank sensors and a couple of different igntion modules on it. my ground at mod. is .0036 on voltage drop. has had diff. pcm. removed alt. fuel injectors and ignition coils. any thoughts.
