I've got my car at the dyno to be tuned. Here's the problem:

MAIN PROBLEM

When the car is cold, it will start right up. But, if you let the car run a little bit and warm up and turn it off, it won't start until it cools down

What should we be checking? My tuner said that the spark coming from the plug wires is more yellow than blue.

MINOR PROBLEM

It's getting plenty of fuel - in fact, at idle it is pushing 75 - and we can't get that number to come down at all. He was wanting to get it around 45. What should we check here? I've got Ray's big pump pushing through -6 lines. Regulator is SX brand.

Thanks for the quick replies as I'm paying for dyno time as you are reading this
