LSx Cranks & Runs For A Second dominator efi 
I have an LSx 402, 234-236 115 LSA, cam, FAST 102 with a NW 102 TB, Holley 160 lb/hr injectors, all stock sensors except ZR1 3 bar MAP sensor 24x 1x cam sensor, GT4788 turbo. All fuel lines are -10, fuel pressure regulator set to 50 psi. Car cranks & starts for a second, then stalls. Used the turbo LSx base calibration and configured it. I also did a system log, no idea how to post them on here. I have checked all wiring a few times, including troubleshooting voltages. Any ideas would be appreciated.

So I used the turbo tune with DBW and set everything for the cable tb and iac from the ls custom cal. Do you happen to have a screen shot of how yours is set?

Figured this out did not supply power the the relay that powers the fuel pump. That is also the system relay sooooo because I was not using the fuel pump trigger I did not think i needed to power it.
