In a Volvo 740 Turbo, some components may have their own direct ground connections while others may share a common ground point. If there is an issue with the common ground point, individual components may still function if they have their own separate ground connections. It's important to check all ground connections to identify and address any issues causing electrical ground problems.

The Mercedes-Benz ML 320 center console is held in place with six retaining bolts. Remove the retaining bolts and the center console will come loose.

i have 89 gle it was doing the same thing , and it was the fuel injetor relay (black 1 undre the hood) I have a 1991 740 which suffers from no start when hot (engine turns fine). Apparently, and this is from a Volvo trained mechanic I'd trust with my life, the fault in these earlier models lies with the fuel pump relay (which he's replacing in a few days). The relay lies behind and slightly above the fuses which are accessed from behind the ashtray, and in an emergency may respond by being tapped a couple of times. Otherwise wait for around 20 minutes and try again.

If both speedometer and odometer do not work, usually the pulse signal are missing. E.g. the wiring coming from the rear differential where the sensor is located, can be deteriorated (broken or shorted).

If speedometer only is inoperative, it is easiest to change the whole speedometer. To repair it, you need to be able to work on electronics, disassemble the speedometer unit, access the printed circuit board, and usually replace the leaking electrolytic capacitors on that board, as well as clean the circuit board of the electrolyte. Some other components may be broken also.

The fuel sensor (which I'm assuming is the sender for your fuel gauge???) is an in-tank sensor on the float valve unit. To access the unit, you'll need to locate the large nut mounted to the top of your fuel tank (6" dia approx.). On our wagon/estate 740GL, this is located under the carpet in the cargo area, driver's side. Fold rear seats forward, remove carpeted panels. You will find a black metal, square cover plate held on w/ 4 screws. Remove it and you'll find the Fuel tank access. The fuel float, pump, sensor are all on the same assembly, but all pieces are replaceable. The float valve is quite expensive, but if removed and work carefully, will still function after pump or sensor are replaced. We found that our float was bad upon reinstallation and wouldn't register below 1/4 tank. It was not a problem with the sensor, but a stuck float valve. Hope this helps.

Check the following....battery connections, look for loose connections, corroded connectors or cables. Check connections at the starter. If possible (if you have tools and know how) check for proper voltage at the starter.

Movement

A general question will net a general answer. The short answer is around 3000lbs, give or take about 250 pounds, depending on options. Automatic transmissions add about 150 over the manual, and wagons another 250. Basically, if its a turbo wagon with auto, it will be about 3300, if its a base level sedan with manual, it will be about 2850lbs.

Adjust or replace the back up light switch, located somewhere next to the shift lever.

bad head gasket.

hey , you have a ground problem , in the front right fender you will notice a series of wires that are no totally secure clean and reconnect . water is making a bridge for u to have a goog ground. good day

Six gears

on the brake pedal bracket

If its the same as the 1990 740 GL: Often caused by failure of tiny plastic gear (underdesigned) in odometer that blocks odometer motor, which is powered by the same circuit board as the speedometer, thus interfering with it. Also the speedo lift-out plugs (5 tiny underdesigned plug pins) can have intermittent contact (test by flicking clock adjust rod). Remedy: 1. Remove damaged planet gear (and replace if possible; if not, at least you have a speedo so you don't get booked for speeding). 2. Solder wires to circuit board at back of plug pins and feed them through to back of main instrument board and solder to relevant points (check with meter what goes where). PS I carefully hacksawed off a large section of perspex on the speedo case to gain access - the only other way is to remove faceplate of speedo that's securely glued on and probably wouldn't survive intact if pulled off. Happy cobbling! BUT BEFORE DOING THIS check that you are getting a good signal from the diff hall effect speedo sender. If your ABS light comes on its a good bet you need to check those wires.

LEFT! Surprisingly the bolt is a normal right-handed thread

If you are referring to the RPM riseing and falling by itself (Hunting) you might want to check to see if the intake is clean. I have had problems with my 740 not wanting to idle when the throttle valve area is coated in oil and grime. After using an approved spray cleaner it idled correctly.
