Hi There is a black plastic cover with four torx screws under the bonnet & close to the windscreen (it also forms the fuse cover) The fuel pump relay (also known as fuel injector relay) is the pink/red one and once you pull it out you can see written on it "fuel pump controller" or words to that effect.
Not so sure if there are relays for each injector as I believe the ECM or Electronic Control Module (located in a black box close to the overflow bottle) controls these injectors with low current switching; there should be no need for relays as the current draw of the injectors is low.
If the fuel pump relay is faulty it will give the same symptoms as lack of fuel. There is a shraeder valve on the right side of the fuel rail (looks like a tyre valve cap) Once cranking and experiencing a no-start condition remove the shraeder valve cap and press it. If no fuel squirts out either the fuel pump or fuel pump relay is faulty.
My own fuel pump relay had multiple dry solder joints. Once these were re-soldered my 850 sprang back to life after months of bad starting. Hope this helps.

Where is the fuel injector relay located on a 1994 Volvo 850 turbo?
I believe all the relay's are located behind the fuse box in the engine compartment (back left section of engine area). You have to unscrew 4 screws and carefully pull of the whole fuse box to reveal the relays underneath.Hope this helps!B:The Fuel Injector Relay, however, also called MAIN relay, is located above the radiator, under the plastic (gray) cover. You'll have to lift that cover up and pull the relay out by sliding it off. It's color gray and part # is W0133-1627788 (Kaehler)
