Car starts but dies. Out of ideas help!

[built420]

I've been working on my car now for th last 4 months. My car use to crank and never start but now it won't stay on. The timing Is good, compression is good I have spark and I have fuel. I put a new ecu and that solved my no start problem but now when I start it it stays running for 30 seconds then dies. I also have really high fuel pressure 100. My car is a 95 Mitsubishi eclipse this is my daily driver and also my project that I'm turbocharging. But can't have a turbo 420a if it doesn't run. Any help would be greatly appreciated! Please help me I'm tired of this thing sitting around and not being able to drive.

Without a mod list I'm just going to assume you have an AFPR based on your info.

"I also have really high fuel pressure 100."

Turn your fuel pressure down to 43.5 psi and try again.

I don have an adjustable fuel pressure regulator on it. The car right now is basically all stock.

could be something wrong with the fpr...

Well the car is getting to much gas and stalling out. Just learned I think it could be the throttle position sensor? Does that sound like it could be it.
