You probably knocked the fuel pump relay loose or possibly the EEC relay ( the pump is indirectly controlled through the EEC relay) or did something to the relay wiring - like lean on it while working. They are on the fender apron on the drivers side just where you would lean over to do head work or work on he distributor. It should click when you turn on the key, if it doesn't --no start.

Oh yeah, the engine turns over good, I just put a test light on the dark green/yellow wire on the fuel pump relay and turned the key to the on position, the light lit for about 2 seconds then no more power

pull the dash apart so you can get to the tank switch, and check for power. you will only have power for 1 second when key 1st turned on, then unless there is a signal from the distributer, the pumps will shut off. I can't imagine both pumps going up at the same time. did both work before you made the repairs?

I found a fuseable link connected to the starter relay, checked it and there is power, The fuel pumps are not coming on to do any priming, I checked the selector switch, it is getting a weak signal ,on tank 2 and no signal on tank one, but the power coming into the switch is very weak and goes off after a couple of seconds.
