dragonflysea Posted September 10, 2007 Report Share Posted September 10, 2007 Was no the way to the gas station (just one block away) when my car started sputtering and died. I am 100% certain that I ran it out of gas. No loud clanges or bangs when it died. So, I grabbed my emergency 5gallon gas can, go and fill it up, lug it back and pour it in my tank and *poof* nothing! The car cranks and cranks and cranks and won't turn over. Removed a spark plug to see if maybe i flooded with my foot on the gas trying to start it and to my dismay the spark plug was bone dry. I do believe I hear my gas pump hum when I turn the car on but there is no gas reaching my engine. Being a 1st time Volvo owner and having bought it used, I am clueless about its quirks. The owners manual was missing when I got it too.. So, I come here asking for help.Is it maybe vapor locked now, did it maybe suck something into the gas line when I ran it out, do these cars have a manual pump reset somewhere you have to use after it runs out?Any thoughts, suggestions or past experiences would be greatly appreciated.Thank you,Michele Link to comment Share on other sites More sharing options...
erikv11 Posted September 10, 2007 Report Share Posted September 10, 2007 The fuel pump is cooled by the fuel flowing through it. If you ran the pump dry, there is a good chance that you burned out the pump. Usually they do not hum when this happens.You can check for fuel supply a little easier than pulling the spark plug: there is a Schrader valve (like the air valve on a bicycle or car tire) at the fuel rail. Remove the cap (usually blue) and press the center pin, if the pump is working then it will squirt gasoline out of the valve when you press the center pin. No fuel at the rail would probably mean the pump is gone in this case. Link to comment Share on other sites More sharing options...
Jippi 855 GLT Posted September 10, 2007 Report Share Posted September 10, 2007 if you hear the pump then try to prime it, turn the key all the way without starting it about 5-6 times then try to start it. im assuming that its an 850? Link to comment Share on other sites More sharing options...
dragonflysea Posted September 10, 2007 Author Report Share Posted September 10, 2007 To check at the Schrader valve, should I have the key in the on position? And really noob question but where is this valve located? Engine or by the fuel pump/tank? Link to comment Share on other sites More sharing options...
RedTurbo850 Posted September 10, 2007 Report Share Posted September 10, 2007 ^It's on the fuel rail. The metal thing that goes accross the engine. Link to comment Share on other sites More sharing options...
dragonflysea Posted September 10, 2007 Author Report Share Posted September 10, 2007 To be specific this is a 1991 Volvo 740 2.3LI have been looking all over since I saw mention of this valve, and I don't see anything like that on this car. Do you by any chance have a link to a picture of its location.Unfortunatly, I barely qualify as a shade tree mechanic and have always owned Fords. I know them pretty well and can fix most things on one.. but this Volvo, I love it way more than my Fords, just so completely "Blonde" about its workings and all the ppl I know who work on cars have no experience with volvo's either Thanks,Michele Link to comment Share on other sites More sharing options...
erikv11 Posted September 10, 2007 Report Share Posted September 10, 2007 :o I am so used to 850 questions that I did not read the make/model in your post. sorry about that! My response was meant for an 850 so keep that in mind. I have never worked on a 740. That is a RWD car, someone in that forum can probably help you out ...I do not know if your car has this Schraeder valve. But if it does then it will spew fuel when the key is in position II, basically after the fuel pump has primed like it does every time you turn on the key. That is IF your fuel pump is in the tank like an 850. Maybe this will be helpful: the 850 actually has two Schraeder valves, The other place is before the fuel filter, under the car near the fuel pump. Basically trace your fuel lines, look for a valve sticking up off of it. It will be obvious if your car has one. Link to comment Share on other sites More sharing options...
Volvoteen Posted September 10, 2007 Report Share Posted September 10, 2007 this is a Tbricks question ...they'll help ya out!edit: just copy and paste what you have said here Link to comment Share on other sites More sharing options...
dragonflysea Posted September 11, 2007 Author Report Share Posted September 11, 2007 See.. thats just how unfamiliar with Volvos I am.. Didn't know it was a RWD. I've only had the car 2 months was a straight trade for a Ford taurus gas guzzler.. Haven't really had time to look it over and learn much about it. 1st bit of trouble I've had outta this puppy and its got 160,000miles on it.I've looked all along the engine fuel tracks and there is no Schrader valve that I can find. I do know it has an in-tank fuel pump and the fuse box in the consol by the gear shift has no blown fuses (pulled every one and checked).I put a stethescope to the fuel tank and turned the key to II and i hear a very faint hum.. Hope this means the pump is still working.. But I get the sense that if it is, its just barely.. So, to add to my questions:Do I have to drop the tank to change the fuel pump on this car or can it be worked on/replaced by going thru the trunk?Is there any valve or any way to prime the fuel lines on this car to purge any air it may have sucked in before I dive into replacing the pump? Thanks again,MichelePS.. TBricks Question just cut and paste.. whats that mean? That another forum? Link to comment Share on other sites More sharing options...
Ronny Posted September 11, 2007 Report Share Posted September 11, 2007 The fuel pump is accessed through a cover plate. It will be on the left side of your trunk floor, not in the spare tire well but up on the deck behind it. You'll have to lift the carpet or whatever is there. Mine is a wagon but the location should be the same. The fuel pump is part of an assembly that is in the tank, it's held in by a big plastic nut and you have to remove some hoses to get at it. Be sure you're confident about this before you attempt anything because you're dealing with gas and one little spark and you'll be lighting your own funeral pyre. As for the "schrader" valve, there is a rubber hose that comes up from the fire wall and connects to a steel line near your fuel rail, which is where the fuel injectors are. You can disconnect the line here and check for flow but use 2 wrenches and be very careful, if the pump is working properly, the gas will really fly out of that hose. Put it into a jug with a small opening and have someone turn the key on and be ready to turn it right off again. The best way to do this is to attach a pressure gauge but it doesn't sound like you're up to speed quite yet. The pump is controlled by a relay that is in behind where your fuses are. You have to remove the little cubby thing above the ashtray for better access. The relay is the white one to the left I believe. Just please be careful, and get some help if you're not sure. A good independent shop should be able to diagnose this for you. I'm sure there are people on here that can help you find a good volvo "indy" in your area. Add your location to your profile and that would help.You could be dealing with a clogged sock on the fuel pump, that's assuming the car has seen dirty gas over the years and there is an accumulation of sludge in the tank.

Jippi 855 GLT Posted September 11, 2007 Report Share Posted September 11, 2007 remove the fpr and check it, maybe hit it against the side of the car and try to see if it works. Link to comment Share on other sites More sharing options...
dragonflysea Posted September 11, 2007 Author Report Share Posted September 11, 2007 Looked and looked. This car has no schrader valve that I can find. Was looking it over today when I got in from work, tried to turn it over and noticed a distinct absence of hum from my fuel pump now so I am very certain that it is completely dead. Trying to find a replacement from local auto shops I am being asked if this is a "Regina" fuel system or not. How would I know if it is Regina or non-regina? I plan on taking the old pump with me when I got to get the new one, just would like to know which fuel system it is before hand because some stores only stock the non-regina and some the regina style pump.. Hate to waste a trip in a borrowed car. Link to comment Share on other sites More sharing options...

Hate to waste a trip in a borrowed car.I use to have a 740 regina system tap the bottom of the fuel tank, check fuses and relay behind fuse block it is a white one and go bad often. If you take a picture of the top of the airbox I can tell you what system you have Link to comment Share on other sites More sharing options...
