Don't worry about an ECU... you don't have one.
It's your fuel pump relay. You'll find it underneath the drivers side
of the dash. They go pretty commonly on older Volvos (usually between 120K
-180K miles). They're not cheap (about $50 from the dealer), but are at
least very easy to replace. You can test your old one by removing the
cover and manually closing the relay, although I'd bet that you'll be able
to tell visually that it's bad (usually there's a burned section on the
circuit board)
That's probably NOT your only problem. The relays don't just go
because they're old... they get too hot from the fuel pumps pulling too
much current. That means clean your fuses, if you haven't recently change
your fuel filter (they're big, but they still need to be replaced eventually)
check that your in-tank pump is working (pull the fuse for the main pump,
manually jumper or close the fuel pump relay and listen). If the in-tank
pump isn't working (or the line between the in tank pump and the main pump
is leaking inside the tank) you're overworking your main pump. After
checking the in tank pump and replacing the fuel filter, check the current
draw from the main pump (connect an Ammeter across the fuse holder with
the fuse removed). If it's drawing >8A, your main pump is on its way out
and will need to be replaced soon (test the pump LAST since the in tank
pump failing or a clogged filter will cause it to draw more current)
