HI i have a 94 olds 98 and it has no spark in cold weather.When the temp drops to about 35 degrees it will turn over but no start due to no spark.IfI take it inside a heated garage in about 5 minutes it will start.If I take it outside and wait about 5 minutes it won't start.I've replace the brain, ignition module,coils,spark plugs &wires, and the crankshaft position sensor with no luck.Also when the car is running it runs perfect.This last time the temp drop the car shut off whileI was driving it [this isthe frist time that happen].Please cananyone help me?P.S. Is it possible thatmaybe the alternator can be surging and cause this?I'm lost S.O.S.Edited by: dtoyss
