[Es2] e//S2 in need of help

Well, the e//S2 stopped running on Thursday.
I was driving normally and it just shut off. All the dash lights lit so
it was not a complete electrical failure.
I thought it was the fuel pump but after some troubleshooting I found
the fuel pump works.
Then I thought the relay may be shot. When I went to remove the relay
the relay cover came off. Upon trying to remove the rest of the relay I
bumped the contacts and the fuel pump came to life.
So I tried another relay but the new relay still did not allow the
contacts to close. So, I have a signal problem to the relay - uh oh...
I tried to start the car but holding down the contacts allowing the fuel
pump to run. Still no start.
I pulled a coil (1.8t conversion) and found I was not getting spark
either. Again, likely a signal problem.
So, in looking at the electrical diagram I figure the ECU is ether not
getting a proper signal into it or the ECU has sh*t the bed.
Any suggestions as to where to go next? Remember, this is a conversion
so a bad signal is easily a possibility as I did find some
less-than-optimal connections during my ignition problem last year.
Can I have my ECU tested somewhere? Do the ECU's die on the '92 S4's
