My 1987, 190E, 2.3 starts fine when cold, but when warmed up and shut off,
will start right back but if shut off and sits for a min or two it won't start for a hour or more. I have replaced complete fuel system, overvoltage relay, everything from the fuel tank on except the fuel pump. Car runs great in town and on the road, I just can't shut it off and expect it to start again unless I wait for a hour or more? Any help with this problem would be of great help!
