First, pull the fuses out of the fuse holders and examine the tips of the fuses. On a European car this old, the first thing you check to see is whether the tips have corroded away on the fuses. Check them all while you are at it because you may have other gremlins lurking in other fuses.
A new frequency valve for this car is quite pricey ($140 on line), but the fact that at one point it was buzzing while the car was shut off suggests that you have problems in the wiring harness that supplies power and ground signal to that valve. I take it that the one you have now buzzes all the while the car is running and shuts off properly when the car is off? I would definitely try to examine the wires from the valve to the computer, disconnecting and connecting each plug to 'freshen the connection' and looking for chaffed or cracked insulation.
You say that you have fuel pressure up to the frequency valve. That means that the next few questions are pointless, but I will ask them anyway - When you say that you jumped the relay, did you jump between the two fuel pump fuses (#4 and #6 as I recall)? Can you hear the fuel pump spin up when you do that? The fact that the car does not start when you jumper straight to the fuel pump eliminates two common suspects - the fuel pump relay which is under the dash above the passenger feet, and the ignition computer which provides the ground signal to the fuel pump relay and is located (I think) behind the kick panel to the right of the passenger feet. I am not certain of these locations because I have never owned a Volvo older than 1987. My cars did not even use a frequency valve.
If you didn't hear the fuel pump spin up when you jumpered it, then we would suspect that the fuel pump may have failed. However, since you say you have fuel pressure up to the frequency valve, you must be hearing the fuel pump. All I can suggest is checking fuse tips and wiring between the frequency valve and computer.
