I have a 92 Mustang 2.3, everything seems fine. What happens is I will start it up & go to the store or whatever.I'll go into the store , than come out get into the car & it won't start??? It will turn tunr over, but won't start, you can smell gas after cranking it over a few times. It seems like its not getting spark? If it sits there a while anywere from 15 minutes to ? it will start. This doesn't happen all the time, it could go for days, weeks or longer & not do it? This past few days it did it twice, I have no clue, hoping someone might have had the same problem before? A friend said maybe its a Circuit Breaker???
