Hey everyone.  Today, I think I need a new fuel pump or fuel filter on my 90 GL.  The fuel pump is absolutely screaming all the time.  Yesterday, it was fine, or mostly fine.  It would buzz a little off and on, normally right after I started the van for a little while.  Today it is constant, and when it stops buzzing (normally when I am turning) I lose fuel pressure altogether.  The difference between the 2 days is that it snowed and got really really cold (I know 5 degrees is not that cold, but this is the mid-atlantic) last night.  I am wondering what this buzzing means. Does it mean I need a new fuel pump? Does it mean I need a new filter? Could it be the pump is cavitating because a bit of water in the gas tank has frozen and clogged the fuel strainer?

Another thing is if anyone lives in the Washington, DC area and knows a shop that can get this changed out for me, it would be great to know of more than just the one shop I have.  My shop is booked up for the week, and I really need my van fixed before next week.

I am sure many of you have changed this out on your own.  Is it as simple as undo the 4 pipe clamps, unplug the wire, put on 4 clamps, and plug in the wire?

I understand the fuel system looks like:

Tank > Strainer > Pump > Filter > Pressure Regulator > Fuel Rails > Injectors

I know where the fuel pump and filter are, but I can't see where the strainer is.  I am wondering if there is a way I can pull it and check what is going on there to be sure it isnt just iced up somehow (though I expect water wont freeze with gasoline around, at least not at 5 degrees).

Thanks everyone,

Jeff
90 GL
