940 GLE cutting off abruptly when driving

My 940 GLE is cutting off abruptly when I am driving. This can happen at
anytime, anywhere, and at any speed (slow or fast). It can cut off when I
am driving up the hill, down the hill, on the curve, or straight.

The interesting part of it is that, after it cuts off, it won't start
immidiately when I try to start it and I must wait for about 5 to 10
minutes before it starts again. Then it might drive for about a half a
mile or a mile before it cuts off for the second time then all I have to
do is wait for about 5 to 10 minutes before restarting it.

Also, I have noticed that, this problem tend to occur and persist more
often when temperature is high (hot)especially. I mention this because,
the other day, the temperature in my area was hot (in 80's), and this
vehicle had been parked directly in the sun till around 2 pm in the
afternoon. When I tried to start it from the ignition switch, it wont
start. I took a screw driver and started it from the starter with no
problem. By the way, if I have problem starting or restarting the car
from
the ignition switch, I can always start it with a screw driver from the
starter. So while I am aware that I need to replace igniton switch, I am
not sure why it is cutting off on me abruptly when I'm driving.

If anyone out there has an idea or can offer a suggestion, I would
appreciate very much.

 

If the warning lights also don't come on when the engine dies and won't
restart, focus on the ignition switch.

Otherwise, a common culprit in random failures and random restartability is
the crank sensor (Hall effect sensor). They are very maddening because the
failures don't fit any pattern.

Thanks mike, but "check engine" light do come on (sometimes)after it dies
and I restart it. So do you think I should still concentrate on the
ignition switch or should I work on crank sensor?

 

hi, I had the same problem. the mechanic replaced the fuel relay switch.
took him 2hr, the relay he said was in a bad spot, part cost 84.00 dollars
and another two hundred for labor. gv

 

I had a similar problem over the spring with a 940. After reading up on
possible causes I bought a new Volvo fual relay from the dealer for under
$50 and spent less than 30 mins installing it. It was a piece of cake, just
a bit of disassembly of the console and ash tray covers. Only 2 screws and a
bunch of snap-together parts, if I recall correctly.

That fixed the problem.

.... fuel relay ... ;-)

 

My sincere thanks to who replied and offered a suggestion or idea. The
cutting off abruptly problem is now solved after I replaced FUEL PUMP
RELAY (or fuel injection relay -as volvo dealer prefer calLing it). I
replaced it with after market part at cost of $41 bucks after I read Opies
and hard;abor replies. Just like Opie said, this thing took about 20
minutes to replaced no repair shop or a mechanic needed. All one need is a
phillip screw driver and the new Fuel relay.
