I don't think it's seizing...it sounds like it's running FASTER than usual,
the normal low whir and click sped up by about 30%. Sometimes it alternates
for a second or so and goes back to the lower pitch which sounds normal,
like the pump is under load from pumping fuel against the built-up pressure.
That's why I'm wondering if the pressure accumulator is bad. I thought the
accumulator was there to help hot starting and prevent fuel boiling. I just
changed the ignition coil a few weeks ago?! Another reason I don't think
it's the coil is why would the pitch of the fuel pump change?
