My baby won't start...

So I have a 1990 hatchback, KA24E. Was driving a steady 55mph in 4th down the highway, lost throttle response completely (cable still opens the throttle though), took her out of gear so she stalled out and pulled off the road. Try to start her back up, starter cranks but the motor doesn't start.
Got a tow back home, a few miles away, and took a look. Note that it was raining hard at the time this happened and there was some flooding on the roads so consider possible water damage:

-spark is sent to the plugs without fail.

-fuel pressure is fine to the rail, but my guess is it's not being injected due to an ecu issue or grouding failure, likely from the rain (it was raining so hard the cabin was leaking a little, which may have shorted something in the wiring around the ecu).

-I have the ecu sitting in two pieces on a table, there is some light rust and corrosion just from age but no major burns. there is slight water damage on the outside of the case but no evidence it penetrated to the board. the ecu does power up but returns a 55-No Malfunction when checked for codes.

-timing chain is intact, as the camshaft spins and the valves open and shut...it is theoretically possible it jumped a cog, but I'm hoping to rule this out as the engine was under no real stress at the time (cruising at 2500rpm, no accel) so I don't see how it would happen.

Any ideas on what I can test or work on to get her back on the roads where she belongs? I don't have a full garage to work in but I've built this car up from where I found her in a parking lot not running at all so I have plenty of tools and know my way around.
