Ok I am need of some help. I have a 2002 WS6 that I have installed. I start it up and everything is good. I can run RPMs up no problem. I can drive with no issue except when i come to a stop it will idle down and shut down (this also happens after warm up at an idle. I am running a aeromtive pump AEI-11109 325GPH 45 PSI with a Race Pump Regulator, Fast Rails with stock injectors. Any Ideas?

 

What is your fuel pressure at the rails? It should be around 58 psi.

Good luck.
Bill

 

Do not know that right now but I am installing a gauge later.
