1997 Honda Accord runs good cold

Car is getting up to operating temperature the entire fuel system is new. This week as soon as the car would start I couldn't give gas at all it would stall also it has gotten harder and harder to start. I'm thinking crank sensor or cylinder position sensor or a bad ECU. I have changed everything else.

I would like to update everyone after throwing the kitchen sink at the car new ECU crank sensor and distributor the car got harder and harder to start where eventually it wouldn't at all. I went back to the basics, and I wasn't getting injector pulse. It turns out the engine harness has a short and that was my problem. But thanks everyone for the help.
