Well ill start off with what I had. I have a 1993 lightning with a stock 351 with a vortech v2 an I was running 32# injectors with a fmu. Last week I removed the front fuel tank an went with the phantom fuel pump and also removed the inline pump and fmu. truck ran good but was still running out of fuel at top end. I got 42# injectors and put them in the truck an followed Sstock tuning FAQ, The truck will not start unless I have opened the throttle till about half way or so no matter what changes I make to the fuel crank pulse width. I started at 38# in the injector multiplier an worked my way to 42# and almost change. When I get it started it takes a minute to clear all the fuel out then it will idle at 13:1 a/f. What else is there to change to correct this?
