Too much timing?

Soooo, when off boost the pump makes some strange noise. When on boost the sound stops. What could be the problem? Tried retarding the timing a little but does the same.

Simple solution. Always be on boost

If that's defiantly coming from the pump, I really wouldn't start it again until you sort it.

It's been doing so since it was rebuild 2 weeks ago.

Sure its the pump? Just sounds like a vibration to me lol

[SonnyRoby]

No no. It's the pump/injectors. When it rev to 2500 you can hear that rattle.

[Tom]

Screwdriver on the pump, ear on the other end and rev, see what you hear

Lol that sounds epic!! haha love advance like that (although will kill your block long term!!) Does sound like your fuel timing though... knock your pump right back and see if it changes tone - if not it'll be something else.
