Hi all,
Just got my 87 900s back from a reliable repair shop, it had been dying mysteriously for the year that we've owned it. Previous owner had similar problems, and had another reputable shop run through TWO used engine-computers, to no avail.
This time, for sure, Rocky. This shop said there were TWO fuel pump relays, and they've replaced both, problem solved. What do you think?

(((For the truly bored:
The car would stop in mid voyage, not usually accelerating at the moment of failure. Once dead, the car could not be restarted. Spark=fine. Fuel-pump=silent. Usually, I'd take out the two relays that power fuel-pump and engine ECU and swap them or just remove/insert them to make sure they were clean. Usually this (or just the time spent waiting) would fix the problem.
This last time, however, it was REALLY dead. I used the +12v supply to the rear-window defroster to power up the fuel pump, and the pump livened up happily. I could even hear the pump's noise in the (silent) engine compartment, though the fuel rail. But no start: engine turned, spark flew, pump whined, but no engine.
It would seem that these guys have simply entertained themselves while the problem fixed itself.
Thoughts: Occam's Razor might point to the engine ECU, after all, this one was used too. But I wonder about the MAS... I've never had one fail intermittently, could that be it? (I know there's not really a decent test, the resistance-check is subject to some real anomoliess--so sayeth the Volvo MAS expert for Beck-Arnley)
I'm open to ideas, weird ones as welcome as others.
