looking from the front of the engine the firing sequence on the distributor is 2,1,3,4 i.e the right hand terminal on the distributor goes to number 2 plug second one goes to number one plug third to number 3 plug and fourth to number 4 plug
The Volvo design has a pressurized cap on the overflow resevoir. It's rated for presssures of 1.5 kPa for many models, doing the same thing as the metal cap on the typical American brand cars.
To replace the distributor cap on a 1990 Volvo 740, first disconnect the battery to ensure safety. Remove the screws or clips holding the distributor cap in place, then carefully lift it off. Note the position of the ignition wires before disconnecting them from the old cap, and then attach them to the corresponding terminals on the new cap. Finally, secure the new cap in place, reconnect the battery, and start the engine to ensure proper installation.

Probably - remove distributor cap and look
To remove the distributor cap from a 1991 Volvo 740, first ensure the engine is off and disconnect the negative battery terminal for safety. Then, carefully detach the ignition wires from the cap, noting their original positions for reinstallation. Use a screwdriver to remove the screws or clips securing the distributor cap and gently lift it off the distributor. Be cautious not to disturb the rotor underneath, as it should remain in place.
There isn't a distributor cap it has a coil pack and it is located in the front passenger side it is a rectangular box that the plug wires are connected to
if's it's a 1.5 or 1.6 ltr. it's in side the distributer cap.
Cylinders are numbered from the front, 1 through 4, and the wires go from top to bottom of cap, 2, 1, 3, 4.
If it's a B240 engine it is at the rear of the head (i.e., up against the firewall). There are three bolts holding the distributer cap on, two are reasonably easy to get off but the third is a mother. A socket on a flex handle (not a swivel) is recommended. The rotor will frequently be stuck to the shaft. Gentle (I do mean gentle) prying will free it. AH
Depends on which distributer cap you have. If it has separate wires just replace it. If the wires are part of the cap you replace the cap and all the wires. Not one of Toyota's better ideas. Runs $50-60.
distributer cap, low octane gas, or spark plugs i would do the distributer cap first.
