Thanks for the link to the wiring site, you can definetely find what you need there.
I have cleaned and inspected lots of wiring.The car starts first try every try and drives normal now, but still shuts itself off occasionally.On a 15-20 mile trip around town it will happen once or twice, shut off ...

It seems that maybe whatever has been causing the battery to be weak at times is responsible for or at least related to the relay problem.
The relay is definitley hot and the area where one of the 6 wires(big/brown) plugs into relay is brown(burnt).I tried a new relay the day it first happened and ...

I fixed the leak, the problem now is that fuse #1(fuel pump) keeps blowing and the f.p. relay clicks repetively when the electricity is on.I tried to start the car today to check the filter for leaks and it started no problem. I decided to drive it around the block and before I made it home it shut ...

This is the same '85 760 as the one in the forum under 'fuel pump relay'.
The car will start now every time, the problem is that the fuel feed line(3" line between the filter and the pump)will not stop leaking.
I have tried everything I can think of..tightened more, loosened more, used 2 washers,3 ...

Here we no/go again.
I was driving along 2 days ago and the car just quit running.No warning, no sounds, no warning lights.Temp normal, 1/2tank gas, driving in neighborhood doing about 30mph.
The only indication that something was wrong was fuse #1(external fuel pump) was blown and the fuel pump ...

Just a quick update on the previous problem.I thought the fault was in the plug wires so I replaced with new.Although the problem of hard/no start stopped for a while, it started doing it again about 1 week ago.It went from starting on first try to 2 tries, 3 tries, 4...and today I was trying to ...

What would it mean if the car wouldn't start try after try... and then I pulled the fuel pump relay, tried to start it w/relay out...and the car started and shut off after a few seconds...of course(no fuel).
I put the relay back in and it started and ran fine.
Just curious.This happened twice while ...

Thanks.I hope she'll keep on spinning!
Thanks for the help, it's good to know I'm not the only one still learning. ]

I plan to get a new canister, it's such a simple part to replace it would just take minutes.
I wanted to replace it when I clean my throttle body, but I'm actually having a hard time finding the gasket locally, I've ordered one online and when it arrives I'll (if I find one in time)replace the ...

Yeah, I'm definitely getting new plug wires, mine are not the originals but they're 3 years old and an 'el cheapo' brand .
In my 3 years of experience w/ this car, my first Volvo, I've found that when it comes time to replace a part, go w/Bosch-Volvo(i.e.'the most expensive') parts whenever ...
