The only thing i can think of that would cause this is a bad washer switch or bad washer relay,if you could locate the relay you could simply pull it out that would fix ya for now.Hope this is helpful to you!!!

Diagram for fuelline 940 volvo


If you are intending on replacing the check valve washer, it's recommended that you replace the check valve at the same time. If you try to match this it's a best guess and if you miss, you are guaranteed a leak and a potential fire hazard as well, not to mention possibly burning out the main pump. If the main pump fails, the engine will not run.

Here's where I get my Volvo 7xx 9xx stuff at the best price with the best service (and your part complete with washer is here, $15.95):

Does the pump run? If not does the pump get power for 1 second when the key is turned to run position? If it does have power then the answer is very obvious, the pump is defective inside the fuel tank or on the rail which ever you have.

My car has a tendecy to shutoff or die while driving. The altinator is fine


You probably need to tell us more.

For example, if things like the fan, wipers, etc., also went out at the same time, then I would suspect it was an arcing ignition switch.

If it happened most at high speed, but would restart at idle after stoping, then I would suspect fuel filter or pump.

You could also check the gas tank vent valve, by opening he cap and listening for hissing.

But you could just have a loose connection in the fuel injection harness, the ignition, etc. Hard to tell without more symptoms.

Need a fuel pump or relay and directions for 1991 940 volvo wagon


Try the relay first.
It's a lot cheaper than the pump.
The fuel pump relay, is located behind the ashtray, and above the fuses.
In order for you to succesfully remove the relay, you will first have to remove the ashtray housing, which is just a matter of two screws that hold the cigar lighter.
The fuel pump relay, is the one on the right side:)
Don't forget the thumbs up:)))
& Happy motoring

Main Fuel Pump


Fuses mean short somewhere.Fuse is always live it feeds relay but in tank pump [ fuse#4or#6 i forget anyway visa versa ] is not live until this.Relay clicks once when key tuned to on and once more when key turned to crank engine it is under dash by glove box and loud enough for someone with ear at this spot to hear.In tank pump should not be live until engine starts to crank.
