well first the fuel pump relay is bad, that is easily replaced. next you have no spark. the first thing you do is take the cap off the distributerand crank the engine. if it spins that tell syou thyat at least the tang or gear on the shaft of the distributor is ok and not broken. next thing is remove the #1 plug and use a 1/4 drive extension 6" long and turn the crank by hand until the #1 cylinder is top dead center(put the extension in the hole of head where the plug was and you should feel the top of the piston also make sure you can feel the top of the piston with half the extension this way you don't drop it in the cylinder with the piston at TDC(top dead center) the rotor of the distributor should be pointed at the #1 firing position. IF it does not that means your timing is off and you need to retime it by taking off timing cover and either replacing the belt/chain or gears. now if you do not have a distributor and you have a coil pack there could be only 2 things that won't give spark. either a bad coil or your altenater is bad(the battery is responsible for starting not running the vehicle like alot of people assume. the altenator energizes the coil which inturngives spark. hope this helps you please rate this thanks

Check under the hood for a box containing your fusible links (they look like large blade fuses in most modern vehicles). The fuel pump relay only operates the fuel pump. It doesn't provide power to the rest of the fuel system. Odds are the fuse for the injection system is blown. The inside of the cover of most fusible link cases usually has a diagram which tells what each fuse is. The easiest thing to do is locate that fuse and remove it (with the vehicle off of course) and visually inspect to see if it's blown. If it is, simply replace it and see if that corrects your problem. While you're under the hood you might want to trace the wires back to their origin and check to be sure the harness is not rubbing or chafing against anything that might have caused wires to break and short. It's rare for those fusible links to blow without a reason.

If your air mass meter tests good, the I would tell you to check the HIGH PRESSURE PUMP underneath the Driver's side chassis pump holder-next to the fuel filter.
There are 2 pumps on your Volvo---the in-tank low pressure, and the chassis mounted high pressure. The car will run with the in-tank failed and the high pressure good. It will not run with the high pressure failed. Test the pump by applying voltage to the two terminals.
Another common failure, should the high pressure pump be good, is the HALL EFFECT SENSOR located in the distributor on the back of the engine. Once this sensor goes, it's no start. A rebuilt or used distributor may be the answer to your problem.
