[QUOTE="Arisley, post: 415218, member: 67"] :whs: Just because it is new, does not mean it can't be the FASS pump though. If the CPS does not fix it, leave the new one on there and keep the old one in the glove box, along with a 10mm wrench and a flat head scredriver. And then put a temp fuel pressure gauge on it. You can put a fitting on the fuel bowl, run a long enough hose to the gauge to where you can strap it to your driver side mirror and watch it. I am betting on the CPS though, make sure you get it from Ford, the parts store ones are famous for being bad out of the box. [/QUOTE]
