I am looking to eliminate the fuel pump relay which resides underneath my glovebox. I would like to run a wire from my fusebox to the fuel injector pump just prior to this relay. My car is eating these relays, and I don't feel like having to replace them, or resolder them. So, I am asking those of you with wiring diagrams to kindly inform me of the number which goes to the fuel injector pump...

Thank you kindly

Richard Nell

So, do you think i can attach a hot wire from the fusebox to the 87/2 after the relay?....

Continuing along in the saga of the fuel pump relay, here I am, 6:00am and about 20 degrees, playing with my brick. Lo and behold, the beast starts...the relay is working fine, I can see it functioning perfectly... (i prefer to leave it out in the open where I can watch over it....) anyhow...do I realy need it? or can I jimmy rig a way around it....

Richard -

Does your car have a single 6-terminal relay? 1985 is a transition year, what with the body like a 1984 and the engine a B230 type and the FI system the LH-Jetronic II like the 84 but modified for the B230.

I have the Volvo Green Wiring Diagrams book for 1985 240, so here's the pin outs for the 6-lug relay.

#30 R wire, fat, comes from the 25-amp fuse.

#87/1 BN wire to #9 on ECU, and OR wire to #5 on AMM

#86/1 Y-SB wire to #21 on ECU

#87/2 Y-R wire to a BN-W wire to IAC #3, Y-R to input side of fuse #4 which goes to in-tank fuel pump, Y-R to all 4 injectors, and continuing from each injector a GN-W wire to #13 on ECU, a Y-R wire to Oxygen Sensor.

#86/2 BL-GN wire to #17 on ECU

#85 R-SB wire to #18 on ECD and tho #15 ib ignition switch.

This may be more than you expected. I hope it helps. If you want to own this wiring diagram book, go to www.volvocars.com/lit

Good Luck,
