I was 'testing' a fuel injector, now 1980 240 won't start. What did I do? 200 1980

Clearly I did something that I wasn't supposed to do.

I was "checking" the rear fuel injector on my 1980 245 4cyl MECHANICALLY fuel injected motor. The car was running fine before I did this the "checking procedure," (I was getting a carbon fouled plug every 750 miles or so, which is why it was running fine right before I checked it). Now it won't start. I'm sure it was something I did. Who knows the fix?

I pulled the fuel injector out.
I set the injector up so that I could observe the spray pattern.
I pulled the wire going into the coil.
I tried to start it and nothing came out (but this was probably due to my testing, i feel sure that the injector does work).
I put the wire back on the coil and tried to start. Again no spray and no start.
So then I take the mechanical injector off the fuel supply line (I did not depressureize the system, which may explain my problem now).
I clean the injector.
I put the injector back on and in the head.
It won't start. Continuous cranking and it won't start. Pulling the fuses going to the fuel pumps and trying to start and them putting them back and trying to start, AND no start.

I think I have violated some pressurizing system issue. Anybody know how to resolve it?

thanks,
jon
