I'm dealing with a similar issue right now. This seems to be common
enough that there should be a technical service bulletin or something
but there isn't. I don't have the solution yet, either.

I purchased Alldatadiy for the year and was able to find a ground
distribution map to see if I can find a commonality between the fuel
pump, power windows, and power seats. They all go at the same time.
My first suspect was a ground in the driver side kick panel. That
turned out to be a dead end. I was able to disconnect it while the
engine was running and the engine didn't die. The next suspect ground
is a wire that attaches to the block near the oil pressure sending
unit. I plan to take a look at this one tomorrow.

Some other symptoms that my vehicle has that may or may not have
something to do with the problem:
Oil level light goes on when oil level is fine.
Periodicaly get transmission code P1870 which indicates that the
transmission is slipping. A bad ground could lead to a false sensor
reading being misinterpeted by the computer.
Fuel gauge is not accurate. The tank is nearly empty when the gauge is
reading 1/4 tank.

Iam having the same problem with a 1994 Olds 88 Royale and
everything you are saying is true, the power windows die the same time
that the car won't start. I thought it might be a ground but have no
clue were to look. let me know if you find it. Also interior lights
are very dim.......

I bought a 96 olds 88 and it is doing all of that, runs when it wants to
basicly. I took my out to a big car dealer to have it dyno and they said
it needed a fuel pump well I took the damn thing home and put one in and
it is still doing it. I was just wondering if you guys have found the
problem yet caues this is costing more an more money every day.
