The classic "Hot Start" problem is not from leaving the car in the hot sun. The symptoms are that that when trying to restart a Delorean right after shutting it down or within around an hour once it is warmed up(depending on the temperature) it does not start easily or you have to do the plug swap thing. Normally this is very irittaing like when you run to the dougnut shop (or gas station), shut the car off, and then get back in the car within say 5-10 min and it just cranks and won't start. It may eventually catch before killing the battery but more often then not the battery dies before you can get it started unless you swap the plug from the CPR onto the cold start valve just long enough to get the motor started. This can also be caused by a bad check valve on the fuel pump or a leaky primary pressure regulator but is most often due to the accumulator. On some cars to avoid having to get the cover open and switch the plugs a P.O. wires a switch into the cold start valve so he can do it from the driver's seat. Basically all that needs to be done is to bypass the thermo time switch which shuts the cold start valve down when it gets hot. Doing it this way you can't overdo it, it will only function during cranking (hot OR cold).
