[QUOTE="speed1st, post: 16885424, member: 204572"] So I took the pump out. Changed the filter on the pump. And went ahead and changed the fuel filter again. Also have a new fuel pressure sensor on it. Now my FPDC is at .50. And about every 10 seconds drops to around .23 for about 2 or 3 seconds. fuel pressure drop is around 25.00 and drops to 10.00 to 15.00 just barely touching the gas. I bit the bullet and just ordered a new pump. Pretty sure that’s what it is. I’ll update after I replace it. Should have it by Wednesday. [/QUOTE]
