First thing in the morning car starts and runs, and reaches its average heat range. Once I turn it off, and try to restart (after a few minutes), it will still restart. If I wait an hour or longer, it will not restart on its own. I have gotten it restarted with starting fluid, but it can take one to many many tries. During the winter months, it cools down fast enough to restart (sometimes with fluid). Now that it is spring, it is taking longer to cool down enough to restart (even with fluid). The twist is, if I let it idle, it will heat up to about half on the temperature gauge. Once I shut the car off, it seems that if it has not cooled down to about 3/8 to less than 1/4 on the gauge, it will restart fairly well. Once it gets down to the average range, I have to use fluid or wait till it cools down completely.

I checked the fuel pressure and it looks like it is reaching the lower end of its range (45-55 according to Autozone), about 45lbs and holds steady. I've been told that through another source, a person asked about a problem similar (will not start when hot) and it was suggested the Idle Control Valve. Does this sound plausible? And if so, how would I test it without just swapping out the part? If you have any other suggestions please let me know. Thank you.
