Broken ground to the frame,cracked magnet assembly in the distributor next to the rivets,the distributor hall ic has rust near it,or the vortec 50psi pump is overfuelling.there are 2 different fuel pumps.pressure is 13 psi.disconnect pump and put it on a fuel machine at 13 psi and see how it runs.the fuel pressure regulator can only compensate so much. ground the ecm case directly to the chassis with a jump cable.start with those
