Should the fuel pump be absolutely quiet or is some noise permissable? I can
hear a high pitched sort of sound while in the vehicle. It's surely louder
than I hear also, since 80% of my high frequency hearing is gone.

I'm trying to track down a problem I' ve had since I bought the vehicle.
Initially the engine would just go dead, usually on acceleration shortly after
start up, but only for a second, just enough to cause a very brief feeling of
decelleration. After one or maybe two such events everything is fine. It is not
a 'miss' in the engine but a complete shutdown.  Over the weekend on the first
camping shakedown and even after completely warmed up the event occured about
7 or 8 times.  Caused me to shorten the distance I intended to go, a bit
worrysome.  The next day, no problem at all.

Does that ECU unit fail bit by bit or completely when it goes?

I'll be changing the fuel filter and I think I'll do the ignition wires, just
to improve long term reliability.  I'm thinking to change the fuel pump and
relay too.Any other thoughts?
