my 1996 aurora won't start at first when it started acting up if i turned the key back and forth a few times it would start but the other day it would'nt start at all so i disconected the battery over night the next day when i reconnected the battery it started right up now it is back to not starting again. could it be the ECM because a couple of times driving the gas pedal would lock up so you could'nt puss it down and the brake pedal would get real hard to push i'd have to stop and restart the car then it would be fine but sometimes after it did that it wouldn't always start. what do you think? mike in goshen
