Pins 31 and 31b are (more or less) the coil for the relay, pins 15 and 87 are the closure pins when the relay is active. If you suspect a bad relay, or just want to eliminate it from consideration, jumper the socket positions associated with pins 15 and 87.

If the car starts and runs just fine then the problem is with the relay. You can either repair the relay - I did a writeup on the repair procedure in the database - or just replace it.

From the diagnostic work you have work you have done thus far it sounds like your fuel pump is toast. You can either go with a Walbro replacement kit or get a new OEM (pump only) from Darrell Waltrip for around $100.00. The Walbro pumps are a bit noisier but they seem to last forever.

Help....!
Here is what happened...
~~bought a Walbro Pump and put it inside the original pump housing but NOT IMPRESSED with the result...the inside bottom end rubber round holder for replacement inside pump kind of flimsy, not sure if the spacer spring was solid enough for the new SHORTER pump...
When put things back together got FUEL LEAKING from the pump, which at least worked. Because the fuel pipe connector which is attached to the output of the pump was crushed on removal. When removing the connector there were pieces of red plastic which were the inside of the connector.
~~~purchased a replacement section of fuel line from local Volvo parts dealer, over $60.00.
~~purchased from FCP GROTON a new OEM fuel pump because of my quality issues with the Walbro, probably just being overly cautious, Thank You.
~~~Today went to run the fuel line in and ...here is where I need help...
I can not get the original section of fuel pipe out, because the raceway or through hole between the top of the fuel tank down to the fuel filter is too tight for the connector(s) on the pipe! Tried and twisted, explored, there just is not enough room for the hose.

Can someone please tell me how to buy and install a new section of fuel pump line? Can I just go to the local parts store and get three feet of some kind of line and clamps? There must be special connectors for fuel line, because of safety issues.

As I write my 1993 850 is on ramps in my garage.

Thank you, for any reasonable advice.

how do you remove the hard lines from the fuel pump assembly? do you just pull up or pry on it. I pulled my hard line off a bit and I see a black washer looking thing underneath with what looks like teeth. Do I have to loosen that or something?

I too have a 1995 Volvo 850 glt and needed to change the fuel pump. I bought a fuel pump kit $70 which came with all of the gaskets/sleeves, hose, clamps and wiring connector, I did not purchase the full fuel pump assembly which is that white plastic cradle that goes over the pump, I figured I could use the old one, however when I removed the plastic assembly and tried to take out the pump, the rubber seal disintegrated which was inside at the bottom of the assembly, it broke off easily into pieces, do I need a new seal? I probably can find a plastic assembly on ebay.
The bottom opening of the plastic assembly looks slightly oval, is the rubber seal suppose to fit snug against the fuel pump outer sleeve? how is the pump held in place? And I don't know how to place the spring, does it get placed above the pump or below it? should the pump with filter be dangling around through the bottom of the assembly or should it be snuggly situated with that spring? Please help clarify. Thanks

Can the Fuel Pressure Regulator be accessed the same way the tank can? I was told on the 1998 V70 XC AWD the FPR is on top of the tank?

It should fit snugly but that is more for noise and to minimize fatigue on the fuel line between the pump and the top of the cannister. It will definitely work but, like the old VW commercial, it will work defiantly if not properly re-installed..

When replacing the quick release fittings onto the new pump, I had a hard time getting a positive connection, so I straddled the hose bend with a 13mm open wrench and used that to apply enough pressure to get it seated properly.

Thank you gents! I hope to follow up with my unique experience but for now I just want to credit this site and all of you who contributed. I was able to diagnose and then replace my fuel pump because of you. She's up and running again and not a moment to soon. I have a feeling I saved a bundle and oh the satisfaction of DIY! :D
