Hi

I have a 93 volvo 850.
For almost 3 years now I have had a very annoying
problem. Sometimes when Im driving, the engine suddenly dies. I have to turn
the key to off and pull over to the side of the road and wait for about 30
seconds.
Then the car starts again and works fine. Same problem could happend 2 - 5
times
the first 30 minutes. After using the car more then 30 - 40 min it works
normal and have never stopped like the problem described above. But if I
should stopp the engine for just one minute after been driving for, let say
2 hours the same problem could happen again the first 30 min after the
re-start.

Does anyone have any ideas what the problem could be?

There have been many instances of this symptom in this newsgroup during the
past... and indeed with my car! My fault turned out to be electrical-power
related. I had a 10-CD changer installed and since then the fuel-relay
kept cutting out. Disconnect the CD and all works fine. The garage
initially diagnosed the problem as a vacuum hose collapsing, but I would
imagine that would happen later in your journey as it warms up?!

Not quite the same symptoms, but my car would run fine some days, and then
like you say, just cut out. It took to doing it on the motorway in the
outside lane. Some times it would restart its self, like a bump starting,
some times I would coast to the Hard Shoulder and it would start after a few
minuets, but in the end it would take 15 or 20 mins to re-start. It was
eventually found to be the Cam Sensor on the top of the engine, 2 bolts
later it was all fixed and has been as good as gold for the last 8 months.
By the way, it did end up showing in the Engine Diagnostic's, so it might be
worth finding out how to read them, and then next time it happens pull
straight over and get the code.

I am almost 100 percent sure that this is due to a fuel pump relay
having gone bad. The relay cost about 20 dollars and will fix the problem.
 
Hay, you go to the carshop and they take out your deffect rele in the brain
who is running the elektric signal to the plugs.You engine is now going on a
reserve-link in the computer.
