How to make the fuel pump run on a 240 Volvo: The quick way to make the fuel pump run is via the fuse box. You can make a jumper from a straightened paper clip as in the picture below. I prefer to jump it on the right side, (the fused side) of the fuses 1979-84 jump #5 to #7 fuses; on 1985 up jump #4 to #6 fuses. Be sure the fuse tips aren't corroded, or this may be the problem. If the fuel pump doesn't run doing this it indicates a faulty fuel pump or faulty wiring to the pump. If the fuse blows the circuit is grounded.
Problem: Volvo heater defroster doesn't work on driver's side. Easy fix. It's a common problem due to a lack of vacuum to the drivers side defroster servo. Under the hood you will find the small vacuum hose coming from the firewall that is split where it connects at the intake manifold port. Trim the split part of the hose and re-attach it. Use a small wire tie to make it less apt to split. Sometimes the hose splits where it goes through the firewall. 95% of the time it's that simple a fix!
Problem: Volvo 240 clutch drags, won't completely disengage, grinds going into reverse, cable is adjusted all the way and there is still too much pedal play. Easy fix most of the time. The ball socket is worn where the clutch arm pivots in the bell housing. It's held in place with an 8mm screw on the passenger side on the outside of the bell housing. Buy a 50mm long 8mm screw and grind or file the threaded tip so it has a ball shape. Remove the 8mm screw from the bell housing while holding the drivers side of the throwout arm or fork forward so the pivot doesn't turn while you remove the 8mm screw that holds it on the passenger side.
Now put about three flat washers on the long (50mm) screw and a dab of grease on the tip of it and screw it in while pushing the clutch fork forward on the drivers side to hold the pivot so it doesn't turn. When you get the long screw most of the way in you will feel the drivers side of the arm pushing rearward. The long screw is your new pivot and this will give you more adjustment on the clutch. (More below picture.)
Now put about three flat washers on the long (50mm) screw and a dab of grease on the tip of it and screw it in while pushing the clutch fork forward on the drivers side to hold the pivot so it doesn't turn. When you get the long screw most of the way in you will feel the drivers side of the arm pushing rearward. The long screw is your new pivot and this will give you more adjustment on the clutch. (More below picture.)
The picture shows the tip of the bolt projecting farther than you will need it, but you get the idea. The ideal total length of the bolt should be about 50mm or 2 inches and three washers. By using more or fewer washers it adjusts how far the new bolt or screw goes into the pivot. Obviously in many cases there is no option but to change the clutch if it's warped and drags. But what a nice surprise when you can fix it for less than a dollar without taking the transmission and clutch out of the car!

Volvo 240 front end noise dept:
After puzzling over where the popping sounds were coming from when I backed up then pulled forward I've found that many times the four bolts holding the front crossmember to the subframe weren't tight. Note the arrows in the picture, two on each side of the engine compartment.
Granted there are other things that make noises ... more later.
