Hey guys,
I've been fortunate to not need much assistance lately, but I guess it's about time that I have a problem. I've been having a fuel delivery problem off and on here lately. Here's the deal:
Yesterday morning, while sitting at a stoplight on my way to work the idle dropped from 950-1000 to about 600-650...completely out of nowhere. I proceed on my way to work babying the car cuz it's running like hammered doo doo. I manage to catch a glimpse of my PMS and it shows "0" on both O2 sensors output. My first thought is that I burned up some wires or something. After checking volts at the connectors, I noticed that I have ZERO fuel pressure...again, this happened completely without warning. I've had other fuel pressure problems before; after changing the fuel filter it seemed to go away-the car had been running pretty well. Incidentally, after the filter dried out, I inspected it, and it was clean. So, I try to adjust my FP to no avail...I even changed the FPR thinking the diaphragm had torn or something. Again-no fuel pressure reading on the gage, and the car barely runs.
I can hear the pump running and all seems normal except that the tone of the pump doesn't change (like it used to when the pressure built up). Is it likely that the pump is bypassing internally in the tank? There are no leaks throughout the entire system, the filter is new, the FPR is new...the only thing I can think of is that the pump is Tango Uniform...
Any other ideas? I don't want to drop the tank unless I really have to.
