Hello all,

This is my first post on brickboard, so be gentle. I'm not very familiar with the maintenance/upkeep of my Volvo. However, at willing to give it a shot.

Recently, my 1990 760 Turbo has been stalling randomly while I'm driving it. At first it would happen occasionally when driving. I would stop and start it and it would run fine. Over a weeks time it starting getting progressively worse, to the point that it died at a friends house and would not start up after sitting for a few hours. The next day it started up and I drove it home.

I have been searching the website the last week or so. I bought and replaced the fuel pump relay. The car drove fine for about 10 or 15 minutes, but as soon as I pulled in the driveway and let it sit for about a minute, it died. I started it 2 or 3 times after that with the same results. One concern I have is that when I was using the toothpicks to pry out the clips for the fi relay, one fell back flush against the board the relay attaches to. I can't tell though if it is getting in the way of the relay, preventing it from connecting all the way. If the relay wasn't connected all the way the car would probably not run right? I should have removed the toothpick, but it was in a very tough spot, and I was already rather frustrated with how hard it was to get the relay and the one next to it out in the first place.

I next thought I would try to take out the radio suppression relay based on suggestions from the sight. I have it in front of me, but I do not notice any cracking anywhere. Should I try to solder all the large and small connections just in case? I have never soldered and I'll probably have to learn or get someone to help me. It seems like it's worth it regardless based on what I've read. But do all the connections need soldering?

If this still doesn't work I'll probably move on to the rpm sensor...if I can find it.

Any help would be greatly appreciated.

A big thanks in advance,
-Mark

PS - With the fuel pump relay I may have knocked something loose. My stereo had a short in it and banging the paneling right above the relay board (I didn't know there was anything there) would sometimes kick it back on. Needless to say it took quite a beating for a while...now I just accept my stereoless car. Darn.
