Is my fuel setup correct
LQ9 engine, LS3 heads adn ls3 intake with stock ls3 injectors. I have a holley fuel rail running a return fuel setup. A AEM regulator 30 to 150 psi. The supply runs straight to the fuel rail goes through teh cross over then fills the other side, from there it runs to teh regulator then to the top of the tank. I am not running vacccum yet on the regulator. with the key forward the psi is 58 once it starts at idle it drops to 52ish. This was all fine and dandy until i tried to pull truck out of garage and it tried to die each time i braked then finally died before i got out of garage and now wont start. Ideas? Do i need to keep higher pressure at idle?
