Strange vibration still

[tomc at satx.rr.com (Tom C)]

well, I haven't had a chance yet to try the relay, had yard work to do
( however, I did check my receipts and found I had them both replaced (relay
and main pump)about a year ago, (less than 1000 miles) not that I'm writing
them off, just not looking promising. I don't have any main pump noise
though.

So am I looking at a lean condition here?  How about lifter springs binding?
or fuel filter too small? possibly original injectors in a GX head? Just
putting things out, other possibilities?

Thanks for the help,

  Is your main pump noisy? they do stuff like that... the rev limeter thingy
that is.

    Really? That is one culprit I didn't even think of. I was thinking more
in
    the lines of the stock sensor plate or even the stock size fuel filter

    I will try the fuel pump relay bypass, and let you know.
