Last Sunday, in the middle of trying to move my mom, my van suddenly
started running rough at a stop sign.  Knowing that the a/c puts a
load on the engine, I turned it off.  Ran slightly better but after
leaveing the stop sign ran rough again.  I made it to my mom-in-law's
about a quarter mile away and when I drove in the driveway and pushed
the clutch in it died.  Hard to restart but got it going and made it
back to my driveway where it quite again.  I got it started again and
the idle surged up a bit, dropped down and continued rough so I turned
it off.  Turns over but can't start since.

I don't hear the buzz of the fuel pump when I turn the key on, just a
"clunk."  Am I on the right track to think it's the fuel pump or are
there other things to check too?

It has about 170,000 on the motor.

Thanks. My last tune up was a little over a year ago.
