Just bought an immaculate 1993 850 and it doesn't want to start in the morning! Not real cold weather here in Florida; have fresh gas in the tank. Battery is strong. Any ideas? Thanks

Allan: Try the fuel pressure regulator. It is a small device right below the fuel rail at about the second cylinder from the passenger side/front of the engine. It has a vacuum elbow connected to it. Maybe that vacuum elbow is broken of leaking, which could cause the loss of prime in the fuel system overnight. Also, check the thermo-switch near the thermostat housing (hard to see). If that switch is malfunctioning, it will negate the appropriate signal to the ECU which could cause hard-starting when the car is cold. The ECU needs this signal to enrichen the mixture on cold startups. Good luck!

Have you checked for spark? pop off one of the spark plug wires and stick the end of a small wrench or something in it (BE CAREFUL NOT TO DAMAGE THE WIRE!!!!) Then use a THICK RUBBER COATED tool of some sort (wire strippers, etc.) to hold the wrench about an eigth of an inch off the block. Have someone else crank the engine and watch the wrench. If you dont see any or a weak spark then you might want to check your coil/wires/alternator/etc.

POSSIBLE CAM POSTION SENSOR AND OR FUEL PUMP RELAY PROBLEM, THESE CARS WERE GREAT FOR THIS IN COLD WEATHER.
