Default Re: 94 Honda Civic doesn't start after oil change

I re-soldered the Main Relay and put the key in II position a couple of
times. Both times the pump started right away. I cranked the car a
couple of times. I still doesn't start.
If I depress the fuel injector tip I get a very fine spray of fuel. So,
I think system is under pressure. I don't have fuel pressure gauge. I
suspect that the injectors are not getting the proper signals to open
on time. The yellow-black wire has battery voltage on it when key is in
Position II. Yellow-black wire on each injector comes from the
Main-Relay.

Where does the other wire on each injector come from? ECU? I am
wondering if something may be telling the ECU not to turn on the
injectors. But then why doesn't my check engine light come on?
