Hi, my 95 850 turbo won’t start, any help would be very much appreciated. Last run was the evening before. A trip about 5 miles nothing unusual no dash lights and let idle it idle before shutoff. Next morning car cranks but won’t start. I can’t find spark. Tested the coil and got .5 and 7.7k , close to the .5 and 8-9k the manual says to look for. Also I have an oil leek from the filler cap. I noticed it few weeks ago but didn’t realize were it was coming from. What are the possible causes of that? Would it stop ignition? I also found a broken vacuum line at the intake manifold, replaced it, no help. Earlier I followed a suggestion to disconnect the battery for a while. Did this clear any codes that would have been there? Now when I hook up a scanner it return no codes.
No spark, no codes to work with, what should I check next? Thanks, Bill

I had a similar situation with my '95 855 turbo. It wouldn't start so I drove my backup car until I had time to look at it. I got to playing with it and trying things. I ended up pulling both ECM's from their sockets ( I think one is for the fuel injection, the other the ignition) after that it started right up.

Your oil leak is most likely due to the rubber gasket on the filler cap. Get a new one; they regularly go bad (harden & don't seal.) Although it's a long shot, has oil leaked down into your spark plugs? probably not, if you don't have spark. I'm not a pro with electrical, but is your coil okay? The only other thing I can think of (and it is NOT related to your "no spark" condtion) is that there can be problems with the fuel pump relay. Good luck.
