I recently bought a 1995 escort wagon. It has a funny quirk, if you park it for about 30 to 60 minutes it will crank over but not fire. If you turn the key off, and then to the on position and hold it the for 10 sec or so it will fire up. If it sits less time or longer it will start up right away. Kind of sounds to me like the fuel is draining out of vapor locking, and you have to run the fuel pump for a few secounds, but why not if it sits longer?
