Hello all,

I have a 93 850 with several issues that I need to clear up before I try to sell it. First off, it has been sitting for 2 years or so. long story short=woman.
I recovered the car and had it running about a year ago, I knew that the gasoline had gone bad, so I purged the system, cleaned the dist. cap, changed the oil, pulled the old plugs out cranked on it to get it lubed up, put new plugs in, put fresh gas in and cranked it.

Nothing. did a bit of troubleshooting, no spark.

the coil is getting +12 volts on both legs, is that right? I thought the little module attached to the coil was bad at first, because I was showing no difference between either input pole. I replaced the whole coil assembly. still nothing.

There could be a problem with the engine speed sensor or the cam sensor.

Sorry but I don't have the specs off hand.You can remove the cover for the cam sensor and make sure it is not oil soaked.I don't have a diagram for the crank sensor or the specs.

I will see if I can get anymore info for you.
