      holley HP starting issue

      I installed a hp to my 509 bbc in a 70 chevelle, the only problem i have is starting. When starting it will fire then die sometimes up 6 or 8 times,sometimes it starts right up and when it runs it is great. do i need a check valve in the fuel line?

      Adjust the starting fuel table. Will it stay running when you tap the throttle? Sounds like it needs more fuel. Good way to find out is when it's running, watch the injector rate (lbs/hr) at the various temps, using that value, add 10% to that in your starting table. That will get you close to what it needs.
