My '93 850 (407000) has been amazing but is giving me issues these days.
About a month (maybe two) ago the car started to stall very occasionally while I was driving but only
when I was coming to a stop or stopped at a light. This was occasional and the car would usually
restart... it might not stall again for a week or two at first... it got more frequent and the delay longer for the car to restart... it would crank fine but no turnover... could hear the fuel pump/delivery activate etc but no start... then after a delay of 5 or 10 or 30 mins. ... I turn the key and it starts and drives fine...
So I had a similar thing happen to me with my old 740 and it was a fuel pump problem... replaced the fuel pump in the 850 last week... good for a few days then same issue... read another thread on the board about another guy having stalling issues with his 850.. suggestion was to replace fuel pump relay... worked for him... I waited until the car stalled while I was driving it to see if that was the issue so of course it stalls while I'm at the coffee counter at a drive through ... wouldn't restart... got a push into the lot and put my alternate fuel pump relay (pulled one out of another 850 - same year and color relay #103 under fuse box)
It made no difference... but car did start after a few minutes. I also noticed that the relay I removed was definitely warm to the touch... is that normal?
Did the computer code check a few days ago for fuel system (A-2) and got a 1-1-1.
Last night car stalled at laundry mat and would not start again... went back this morning and it started right off and got me home before stalling just as I turn into parking spot and would not restart.
When I was researching the fuel pump relay the parts list also had a fuel injector relay listed under fuel pump relay... anyone know the difference or anyone have a suggestion???... am at the point where local talent may not be adequate and I have to tow to Volvo dealer 30 miles away... expensive... can anyone help here or anyone had the same issue?? Any Help Appreciated... please.
