Default engine runs for a second and dies out

Well yeah you get the picture this is whats happening right now.

Engine fires up for a second, the turbos generate a very loud whistle that might be some sort of an exhaust leak (which ill fix), but engine wont stay alive more than a second.

Because of that I havent been able to adjust the regulator properly. Im using the A&A kit which utilizes both the stock pump and an aftermarket larger pump. The stock feed line has a checkvalve that shuts closed when the big pump kicks in. Because of that, firing the car up would give the pump enough pressure to crack the valve open, but my guess is that it soon shuts off from lack of pressure? but thats just a GUESS.

What we did was manually ground the big pump to kick in, adjusted the pressure while ignition was "on" (engine not running), got the pressure to 43.5PSI and fired it up, yes it lasted for 1.5seconds this time, but you get the picture same thing.

Dont know where to look, and im trying not to crank it up too much.

suggestions appreciated.

sounds like yet another map issue. What map sensor are you running and what operating system are you using. This could be your problem
