Volvo 240 fuel pump relay ..... where is it?

[justanotherhigh]

Fault finding in the dark as we appear to have no fuel coming through.
Does anyone know where the relay is? -- as this is a 1985 pre-injection model, it's not mounted on the bulkhead where it should be.
I haven't found anything else that looks like this anywhere:

Any ideas before I pack up before the morning? =/

[welshpug]

given it is not injection, will it have an electric fuel pump?

[justanotherhigh]

It's got a mechanical one on the engine plus an electric one on the tank, apparently.
The owners manual gives the (incorrect) relay positions and a fully incomprehensible wiring diagram to go with that.

Not to worry anyway, it's not a problem with that, though I'd still love to know what it was. Spent two hours headscratching at the seemingly ample amounts of sparks and petrol that were present, but no firing going on at all.

Resorted to towing it in second gear for about two miles and that had it running, albeit very very rough.
Gave it some high revs driving and it resorted to its usual self.

I don't understand

Have a look on the left hand side of the inner bulkhead in the area behind the glovebox.
I THINK that is where the relay was on my 2.0 CIS version so suspect the carb will be in the same place. It's a long time since I owned a 240 (one of the best cars I've had - until bonnet came up at speed !) so might be wrong but worth a look.

That was suggested by the manual and volvo owners forum - but it's not there.

No idea if it's the same, but on a 740 it's in the dash, in front of the gearstick/behind the ashtray

As Benzine - the fast that these cars have open looms does not help. They may be moved and relocated in their lifespans. There are a host of relays mounted behind the heater panel controls on mine (an injection model though). I'm about to attack the heater tonight (not working AT ALL... brrrr) so I'll keep an eye out and see if something similar crops up in my travels.

I have found the Haynes to be a guide rather than a bible on many occasions, but i think with the 240 there were a lot of revisions that the Haynes missed in its lifespan.

Cheers benzine, that location has allowed me to find a couple of spares from the scrapyard at least!

There's various unknown relays in the engine bay, but the ones under the dash are literally indicator/hazard flasher and the lamp check relay. That's all. Nothing anywhere that resembles the picture in the original post anyway. -_-

When I converted my 240 to LPG I cut the supply from the fuse box, via a relay, to fuel pump for when running on gas. There is a separate fuse for the pump. What about identifying this fuse and with ignition switched on removing / adding fuse so the relay clicks and trace the sound. In fact can't you do that by switching ignition on and off ?

I'm sure I can trace it out given enough time, just wondered if anyone knew the exact location first ^.^
There's two fuses present for only one fuel pump, I'm a little curious as to why that is though! Unsure if maybe my car is just built up from someones parts box..

My 240GL (2.0 CIS) had two fuel pumps. One was lift pump in the tank and the other was a high pressure pump underneath the car by the tank, together with the fuel filter, so that could explain why two fuse positions.
