Well the wife said it was a hard start yesterday and today it wont start at all. No fire. Pumps white smoke clouds out tail pipe though. I remember this happening to me some years ago and I had to replace a solenoid looking thing. There are two of them---one near the fuel filter and one in back of it toward the firewall---both have two large connectors for wires and two small connectors for wires. I don't remember what each one does or which one I replaced. At that time it worked and the thing ran. If I remember correctly, its the third one that's been put in. Why would these things fail?
