Re: 1988 volvo 740...will start... runs at lowspeed
I have a potential solution, but only if you give good thumbs up though:) It's the fuel pump relay, located behind the ashtray. It's the one on the right, of the two. If you gently twist it l/r, while turning the motor over. Happy motoring

The squeeling nose is a loose or worn out power steering belt have you mechanic replace and tighten the belt, most of the time the heat shield fastener or mounting hole has rusted out and no tuely effective repair can be performed
There is a tool available from most auto parts supply outlets, it is a plate that has a compression bolt through it, you slide the plate into the caliper, and tighten the bolt against the piston, then keep turning until the piston is all the way in. These are relatively inexpensive and good to have for next time.
Here is what I found was the problem with my 1988 740 GLE Wagon.
Remove the phillips screw that holds the cigarette lighter in place. Now remove the ash tray. Next, pull the storage tray and cigarette lighter assembly and lay to the side.
You will see two trays, one with the fuses and one with the relays. The one you want to look at is the relay tray.
On the far left side of the tray and the 2nd relay from the back is the relay that engages the ignition when you turn the key to the start/ Run position.
It is very likely that is simply a bad connection where the relay pprongs plug into the socket in the relay tray.
wiggle and pull up on the relay assembly until it comes out of the tray.
Now just tweek the prongs slightly on the relay so they will make a firmer contact in the socket.
Now put the relay back in the same position it was in originally. Pull it back out and put it back in a couple of times to clean any corrosion oin the contact prongs.
Try to start the car now. This will probably correct the problem.
If not you may have to replace the relay because it may be defective.
