fuel problems....no fuel

Found this '87 900 8-valve for almost free..."ran fine, but stalls at full operating temp, no restart until fully cools down"
After towing home, found that it was getting no fuel at all.
Pulled fuel line from filter to fuel distributor, jumped pump relay. Pump operating fine, plenty of fuel
Pulled fuel line from Modulating (Frequency) valve at fuel distrubutor, jumped relay and ran for 10-15 seconds...no fuel and seems to have "burned up" Mod. valve after continual fuel starvation?...valve buzzes nonstop and after this occurs, circuit to the fuel pump seems to have broken and pump becomes opearational only after replacing Mod. valve (have repeated this several times)
Is the problem directly related to the Mod. Valve or does it relate to the ECU.
Obviously there is some blockage at the fuel distributor, possibly line pressure regulator?
I think that I am on the right track. Mostly out of pride I would like to get this car going without taking to the local Saab mechanic.
Any sugestions?
