well, weekend three and now my new brick has been in the driveway longer than I have driven it (3 weeks out of a month). I just replaced the fuel filter and am still experiencing the same problems.

A little background on what I've looked at/replaced:
http://www.brickboard.com/RWD/volvo/1316585/220/240/260/280/just_replaced_accumulator_wont_idle_hard_start_b21ft_244_240_turbo_fuel_pump.html

http://www.brickboard.com/RWD/volvo/1314240/220/240/260/280/ci_fuel_pump_something_else.html

So basically it doesn't want to start. occasionally it will start but I have to keep on the throttle to keep it running. Any sudden change in throttle position causes it to die. From my tests both fuel pumps make a hum when powered and I do get fuel delivery at the return line (roughly within spec). I don't find any fuel leaks either. Short of replacing fuel pumps, I'm at a loss for the direction I should go next.

The odd part is that it was at least running with the failed accumulator. What could have changed since then to create this condition?
