Are you saying there is no fuel pressure in the line, or just after the filter ? ?
If there is pressure before but not after the filter, the filter is usually blocked.

    I have replaced already the fuel filter before I posted my problem and what I have suspected is that there is something like a leak or something not holding the fuel pressure between the fuel filter and the engine components. Hence! Could be the fuel regulator?

    It could, but also could be the check valve in the pump that prevents the fuel from flowing back into the gas tank.

SOURCE: 99 Volvo S80 water pump replacement

if this helps.. I had the 1998 model S70. the water pump was driven by the timing belt. you had to take the timing belt off just to replace the water pump. it was just a simple bolt on replacement. the only difficult issue is resetting the hydraulic tensioner on the timing belt. the hydraulic tensioner has to be completely taken off and compressed VERY SLOWLY in a vise. then insert a very hard drill bit or (special volvo tool) into a keeper hole, reinstall hydraulic tensioner onto car and reinstall timing belt.very quickly remove drill bit from keeper hole in tensioner and the tensioner snaps back out to put tension on belt. and you are done.

SOURCE: How do I replace the fuel filter on my 2000 Volvo S80

The gas filter is located passenger side just forward of the rear axle. The band that holds the gas filter in place is a pinch band that has a nut welded/formed into it on the back/top side. A 12 mm bolt holds the band in place. The top of the band has a bracket that hold the return fuel line - this just pops off and the return fuel line can be reattached once the filter has been replaced. If your filter has never been replaced there is masking tape covering the pinch connections at both ends of the filter. Remove the masking tape. You need to put a pan under the old filter to catch any gas spillage - it will be minimal. Also the new filter comes with plastic caps on the ends of the new filter - you will want to use them to plug the old filter connectors so you need to take them off the new filter to have handy. Ther is a T off the inlet gas line that has a cap on it - remove the cap and press the needle in the T to relieve any pressure that is on the gas line - If it has been setting for an hour there will probably be very little if any pressure on the line. You can skip messing with the T and you will see about an ounce of fuel that will come out of the filter when you remove the hose.

To remove the connectors push the connector ring away from the filter housing. (I did the front first because I had more room). I used a paint can opener to help pry the hose away from the filter - it is shaped like a can opener but without a cutting edge - a large flat screwdriver would perform as well. It is a tight fit but once it starts to move it will come off. Once the hose is off use the plastic caps you took off the new filter to help hold the gas in the old filter. After removing both ends remove the holding band and place it on the new filter. The two lines will go back on easier than they came off, just push them onto the filters nipples. Put the 12 mm OR 10MM bolt back into the pinch band and reintall the return fuel line.

SOURCE: How to replace electric fuel pump on Volvo S80

It helps to pump out the fuel in the tank if possible, to lighten the load. You'll need to remove the fuel tank from under the car & lower it to the ground and get it into position to work on. Care must be exercised so as not to crimp any lines & to keep any sparks/flames away. An empty tank will explode more easily than a full tank will. The Fuel Pump with the float & any sensors & a fuel sock/filter is the assembly & all are removed in one unit, from the top of the tank by loosening the assembly, the hoses, and disconnecting the plug in.

Once removed, if you are replacing the entire assembly, you may want to check the inside of the tank for debris that you can remove at this point, then reinsert the new assembly as a unit into the exact position it was mounted before. Note the float position as it can't be crimped/jammed or you will have no fuel gauge. (digital camera option-take pictures to review later before & during removal) Once you've got it back into the car & added the fuel back in, or if it has enough still in it, you'll need to prime the fuel system by turning your ignition off & on for a few seconds at a time. You'll hear the fuel pump run when you turn the key to on, leave the key there until you hear the pump stop & wait a few seconds, repeat. This will fill up the fuel system. You may want to take the time to get you a new fuel filter, if you do & replace it, fill it 1/3 full before installing with fuel injector cleaner and you'll give your injectors a good cleaning. Might sputter just a few seconds-no more. good luck.

SOURCE: Emergency fuel door release for 2000 Volvo S80

Copied from Volvo Forums

I had a similar problem w recently bought 2003 S80.Several points: 1) Access your locking selonoid through the trunk interior panel ... loosen a few hex bolts and slide out for maintenance; 2) I fixed my lock by simply using light teflon-based oil (like for bike chains). I exercised it a few times and it works beautifully; 3) Not sure on your model, but gas door on the '03 unlocks when you push the associated release button under the headlight control switch. It is not designed to unlock w the key (again, check owners manual for your year). Hope this helps. master_pre08-04-2007, 09:35 AMYeah, the fuel door on my 2000 S80 is connected with the door locks. In order for it to open you have to unlock all the doors to the car. Sssnake08-14-2007, 03:39 PM Thanks Guys,

I removed the locking mechanism and applied a little silicon graphite and now it works like a charm.

99 Volvo s80 2.9 not taking fuel what could be wrong with it any ideas

First, check the fuel rail and make sure it is building pressure. Take the cap off the nipple (it looks and works like a tire pressure valve stem). If no pressure, first make sure a clogged fuel filter isn\'t the problem. The fuel pump is accessed under the back seat if you\'re not getting fuel to the filter. If that doesn\'t solve the problem, give me more info as to what you have done and when the problem started.

My volvo s80 is hard to start regardless of hot or cold conditions.

I would check the cam timing, and the fuel pressure. If the cam timing has jumped it can cause this problem, also low fuel pressure can cause this problem if the fuel pump or pressure regulator is failing.

2001 volvo s80 no fuel pressure. cranks but doesn't start. checked all fuses all good. no power going into fuel pump

the first thing is to try another key, you may have a bad chip in that key, this dissables the fuel pump, try that first, next would be to test for power at the pump, if theres power and a good ground at pump then you need a fuelpump, you can get to pump by removing rear seat then remove the cover on the floor and you will see pump and wiring good luck.
