Daughter's 1986 240 Volvo wagon wouldn't start suddenly. Cranks, but no fuel flow. Replaced filter and fuel relay ( is there only one?). Timing belt not broken. I think it was the fourth fuse down doesn't get power to it so the presure pump under the car won't run. 25 amp fuse in engine compartment good. Any suggestions as to what to chase down??? Don't have a good schematic or knowlege of how it all works.

"Roll" all the fuses to make sure they are getting a good connection; they have a tendency to corrode.

Has the connector at the battery cable (held in place with a nut on the positive post clamp) been cleaned any time that you know of? Corrosion there can isolate it enough to reduce its ability to supply enough amperage to energize the relay.
