You should Replace both the Fuel Pump and the Fuel Filter for this Low Preassure Issue and the No Start Issue Both.

My 1995 Volvo 850 will not start. I think it is the fuel pump. I tryed a procedure where I removed the fuel pump relay and jumpered the sockets for blades 85 and 15. there was no help in starting the car...


another way to test it
unplug any fuel line you can locate tell a friend to start key one turn only if the line squirts fuel then pump is working and it might need regulator
if not then pump is gone

93 volvo 850 glt changed the fuel pump now car wont start. Engine cranks, fuel pump working, fuel getting to the motor but it wont start. The car had trouble starting sometimes so i changed the fuel...


Check your fuel pressure to ensure proper pressure to the block, also did you replace the fuel filter.

On a side note: 3 things a automobile needs to run

AIR-make sure you have a clean air filter and your MAF (mass air flow sensor is plugged in) if you pulled your breather to innspect anything, there is a possibility that it came unplugged or you unpluged it and forgot to hook it back up, a car wont start without it being plugged in if equiped

SPARK-Make sure your car has juice to the plugs, if the plug doesnt fire the car wont run, if you have to pull each plug and ground them to the engine block to see if they arch. If not trace the problem down (if you changed the fuel pump you have some mechanical skill and should be able to troubleshoot a spark issue)

FUEL-Check for proper pressure, dirty fuel filter(s) and if your system has a return line, make sure your hoses didnt get crossed cause this will damage the engine and regulator.

Hope this helps Thanks for using Fixya.com

Volvo 850 2.0 1995 non starting already fitted new plugs leads cap roter arm cam and crank sencors good spark good fuel presure and no imobliser light on plugs all dry when turning over engine


try spraying some easy start into the air intake while someone operates the starter if it trys to start you have a fuel system fault have you checked fuel pressure at injector rail you need to do this using gauge and check against volvo spec if low it will never run if ok check feeds to injectors using multimeter if no feed check relevent fuses if ok using multimeter check continuety of injector wireing back to ecu if it did not try to start using easy start check timing belt is ok and engine has compression

1993 Volvo 850 wont start...help?!


It sounds like your fuel pump is having a problem with getting the last of the fuel from your tank. The pump also has a strainer on it. The unfortunate reality with the 1993 Volvo 850 is that the pump and strainer are located inside of your gas tank. You can look for kinks or pinched areas in the line but from your description it sounds like the pump is going. It has to work much harder when the fuel is low in the tank.

Hey jkcalli!
Have you checked for any error codes?
Since your car is an 850 you should check your fuel pump relay, which is infamous for causing intermittent starting problems. Open the hood and remove the fuse box cover (4 torx screws), revealing the relays. If one of them is a green one marked 103 you should replace it with the newer, improved red relay. A used relay is cheap and should do just fine. 

Also, you should be able to hear the fuel pump working when turning the ignition to on. After doing this a couple of times the pressure becomes high enough for the pump not to engage. If so wait for the pressure to drop before listening for it again. 
Here's a topic with some info on the relay and how to check the voltage at the pump:http://www.volvo-forums.com/index.php?showtopic=15505&st=80&p=80586&#entry80586 


If fuel delivery is not the problem you should check for spark. If you do not have spark the problem is likely coil, camshaft position sensor or crankshaft position sensor.
Good luck!

No start,can hear fuel pump running,pressure about 48#


probably mine will work...I have the same car....I had the same problem...try this....open the hood,there is a valve, first take the cover off where you raise the engine up manually,I think you might need a island key to take it off,under it ,ther is a cap,unscrew it,and there is a valve like your tire valve,depress it..until the air or gad stop hissing out,if air come out,your problem is solve,try starting it,it should start,or try putting some dry gas in the tank,try several time....good luck

Check the fuel pressure regulator. It is probably vacuum operated. It is located on top of the engine with a small vacuum hose attached.

1993 Volvo 850 fuel issues


it is the fuel pump for sure. If you can hit the tank and get it to run it is the pump. this drain back (hard start after sitting) is a fuel pump issue as well
