Have a 940 turbo wagon that's been sitting for two plus years it's not getting fuel up to the rail have all the hoses off the in tank fuel pump and it's not pumping any fuel out when I pulled the wire harness connector in the fender well and put a test light on the pink I get the light to light up but when I connected and put the probe in the connector I'm not showing any voltage where does the fuel pump get grounded.... What actually grounds the fuel pump that's in the tank to make it work is it a relay is it the crank positioning sensor, and is there any place to get a wiring diagram

Its grounded tw thew wires coming out the rtop

I typed this in a dark part of my living room ,The keyboard junmps around& & Lenovo refusesz to fix it..

Hi,

Go here for some nice Volvo 940 wiring info:
http://www.autoelectric.ru/auto/volvo/940/1993/940-93.htm
This will get you started.

The book you want, your #1 best DIY pal is Volvo Service Manual:
Volvo Wiring Diagram TP3904202 1994 Volvo 940
Look on Ebay, and used book sources, Abe book etc.
It can be found on-line if you get lucky with sleazy search engines
who want to sell it to you from their proxy websites.

The in-tank pump 6/33
grounded at the drivers side tail light 31/11 in the 945
and towards the center from the same tail light 31/13 in the 940 (under the trim)

the fuel pump 6/31 shows a ground 31/31 at the mounting plate with
the fuel filter.

Good luck, Bill
