Ok brickgenius's, a no start/hard start B21FTi. Motor sat since '98. 140K
I replaced wiring harness.
New in-tank pump.
Known good main pump/accumulator.
Known good fuel relay. good click!
New plugs, wires, cap and rotor.
New oil/filter, new coolant.
New timing belt. Notch on crank at zero on cover, rotor pointed to notch on dist. #1
New fuel 5 gallons or so.
Serviced throttle body and fuel dist./plate, etc.
New vacumn hoses where required.
New fuel and air filters.
Known good oil-cooled turbo.
Known good ECU, idle motor control.
Cleaned intercooler, all hoses, etc.
Frequency valve is buzzing.

WHEN, I can get it to start, it sounds and starts like my other volvos, fires right up (ah, problem solved), it will accellerate during this time (didn't go over 3 grand, cold oil, etc.), and idle...about the time you get out to check for leaks, maybe 2-3 minutes or so, the motor will slowly loose power and die! It doesn't sputter, start to miss or anything like that, it simply, slowly dies, like you are choking it. Pumping gas pedal won't do anything.
It will not restart, will turn over (real easy, seems like)
and it will not HIT at all. If it sits for several days, I can restart it, with the same results. This has happened five times or so.
I don't have a way to check fuel pressure.
I have plenty of volume returning to tank, and this line is clear (blew in line until bubbles were heard at gas filler).
Pulled all injectors, cleaned, and have gas flowing, re-installed, new seals.
Have good spark at all cylinders.
Gas smell during restarting procedure.
Put oil in cylinders to try to start (quick compression)...no luck.
Please give me some advice...this is making me (and my wife) crazy! Besides, I'm starting to lose credability!(face) ya know?
thanks in advance!
