I left for a two week vacation only to come back to a problem. My 93 850 cranks but won't start. I had the same problem last winter. Last winter I have replaced the cam position senson. That did not fix it. It was the wire going from fuse 1 to Engine control module that was loose at the fuse tray.....now I have the problem again. Car cranks but won't start. When I came back from two weeks vacation the car was not driven at all and the battery was completly dead.........I have put in new battery.....but still the same problem......CRANKS but doesn't start.......Few match prior to leaving on my vacation the radio and blower fan did not go off when I took out the key from ignition.......for about a month or so I was turing them of manually.....Could this be ignition swith problem? Please help......I love this car when it drives. Oh and I have also replace the PNP swith with a new one as I had the winter mode coming on almost all the time. So new PNP switch and about 10 month old cam position sensor........Still the car cranks but no start......Also where could I find the ground connections, I want to clean them up.........Please help........Thank You in advance....
