Bobs77, Have you had any luck with your start problem. My 78 280z is doing the same thing. IE during hot summer months, its hard to start after it has been running and then shut down for about 10 minutes. I have notice the temperature while running is about 170-180 degrees. Once shut down the engines temp slowly increases to about 210 degrees and this is when it starts being difficult to start. Once the engine temp drops back to aobut 170-180 then it will start normally. I feel like the increase in temp is affecting something but not sure what it may be. IE Could the increase in temp cause the metal fuel injection line to heat up and increasing the pressure in the line?
