SOURCE: 1985 Volvo 740 GLE does not start well when either

Check your start injector (under the intake manifold). If OK, check the air valve. 12 VDC at the connector should mean the valve will move when tapped or shaken lightly. To see if it moves - shine a flashlight through the upper opening...
... and verify that you see light on the other side. After five minutes it should close completely. If no change occurs and you have 12 volts at the connector, replace it.

The start injector could also be faulty. It uses a timed thermostat that opens at the operational standard of 60 degrees F. It will pulse on and off and if it's stuck open or closed, this will cause hard starting. The other possible cause is das Luftmassenmesser (Airmassmeter) has failed. Check for breaks in the fine filament around the meter. Also clean it with air mass meter cleaner (NOT brake fluid cleaner!!) and try your starting again; no change, and it is faulty.

Finally, the fuel pumps could need attention, check the fuel filter, tank pump sock (if the tank pump is very noisy it is failing) and tank pump operation. A faulty tank pump makes the main pump work overtime, and this is a major league problem for these cars.

SOURCE: I would like a diagram

You don't really need a diagram, it's simple. If you open both tail light boxes in the trunk you will see at the connector on the bottom a yellow wire in the first position. That goes to the brake bulb. If both tail lights do not work, make sure you are getting power to the driver side light first, if it is not getting power, the passenger side will not work either, they are in line with each other. If it is only the passenger side not working, the bridging wire could be bad.. try jumping it. Also, make sure you are getting power inside the tail light bulb holder. The metal connections can come loose. If there is no power to the driver side tail light it could be the bulb failure relay, that is the round red relay in the rear left side of the fuse box behind the ash tray/ cigarette lighter below the radio in front of the shifter. You should be getting power to the third brake light in the rear window...that is a different circuit and will not be affected. Try changing out the bulb failure relay, it supplies the power to the tail lights.
