1989 245 No Start, Fuel System? 200 1989

I've got an 1989 245 wagon who has been good to me (420,000 miles on it), but has had some trouble lately. For several months, it had a rough idle when started, for about a minute, before smoothing out. The engine light would come on and indicate a fuel system problem, but wouldn't give the code for what it was (meanwhile ignition system tested clean). During this time, the car ran well on long road trips across the country, starting and running smoothly...

But now it won't start at all. Turns but won't start. I've checked a fair number of things.

-Changed plugs, fuel filter, wires, cap and rotor, tried another AMM (ran similarly), new fuel pump relay, new oxygen sensor, changed/cleaned 25amp fuse near battery. Car has good compression.

When ignition is turned on I hear the fuel pump relay click but when I turn to start it the relay buzzes a bit: due to incorrect voltage reaching it?

This car does have a leak through the passenger side under the dash, but the ECU appears high and dry (took it out and checked it out---it is the infamous pink label ECU, however).

Anyone have any ideas? It seems like it could be a short to me, could anyone suggest some grounds/their locations to check? I'd hate to lose this wagon...
