Is the engine running lean? ------------------ '70 Mustang Mach 1 M code 351C 4V/FMX/3.25 open '72 Mustang Sprint Coupe 351C 4V/FMX/4.30 Trac Lok '94 F-150 XL 5.8L/E4OD/3.55 Limited Slip MCA Member # 47773 "Doubt is not a pleasant condition, but certainty is absurd." - Voltaire IP: Logged
fastbackRb Journeyman Posts: 79 From: Columbus,Ga. Registered: May 2002	posted 05-10-2002 11:26 PM Steve just got it fixed tonight.Yes it was lean and would skip and sputter sitting still. You know it is always the real simple things that cause the most trouble.6 mouths 4 pumps and a new engine agitated the problem so bad we finally found the ground wire to the fuel pump was not good enough for anything more than a stock type pump. I spiced a wire into the ground wire at the tank and grounded it to the frame and had instant pressure. The best way to tell if this is the problem with efi cars is to turn the ignition off and on 6 or 8 times and if the pump does not run strong evey time reground the wire. A 5 mimute cure that lasted 6 mounths and to thimk thats why the man sold it.
