Fuel injection experts needed, no start while it's HOT Options

[mtndawg]

I'm running a 1.7 with original djet.
I drive the car yesterday while it was 100+ here in Sacramento. After driving about 40 miles, I turned the car off. After only 2 minutes I turned the key and the sounded like it was going to start, then died. I cranked it a few more times and nothing happened. i let it cool for about 10 mins, then cranked it again. It started right up on the 3rd crank and ran great for the drive home. I've had this hard to start situation a couple of other times in the heat.

I also have imperfect idle when the engine is warm. It idles between 1300 and 800. I know that's pretty good, but I would like to get it idling at 800 to 850 every time.

All new vacuum lines
Clean trigger points
Clean Trottle Position Sensor
Good MPS
Virtually new injectors
New fuel press regulator
New rubber fuel lines
New screen in the tank
New fuel filter


I have never touched the temp sensor Could this be the problem?...and yes I have read pbanders site many times, that's how I learned to operate on djet.
