How to Install Distributor Cap for 1991 Honda Accord
The distributor cap is the cover that protects the distributor and provides a spot for each spark plug wire coming from each spark plug in the cylinders. The distributor spins underneath the cap, sending a bolt of electricity to each point on the distributor cap. The electricity then travels through the wires to the spark plugs. In the 1991 Accord, the distributor is a round shape and has four spots for spark plug wires, since it came with a standard four-cylinder engine.

Prepare the old distributor cap for removal by unplugging the 2-P and 8-P connectors connected to it. Unplug the two hoses going to the advance diaphragm if your Honda Accord uses a carburetor instead of fuel injection. Loosen the three hold-down bolts on the distributor cap, leaving the spark plug wires plugged into it.
2Coat the O-ring from the new distributor cap with motor oil using your finger. This is done so that the ring goes in smoothly and doesnt tear from friction.
3Take the old distributor cap off of the cylinder head, and slide the new distributor cap on in its place. Make sure that the three hold-down bolts are lined up with their respective holes.
4Unplug the spark plug wires from the old distributor cap, and plug them into the new distributor cap using the same position. If your wires are already unplugged, plug the wire coming from cylinder 1 into the spot marked with an "A" on the distributor cap. From there, proceed clockwise plugging in the wires from cylinders 3, 4, and 2 in that order.
5Tighten the hold-down bolts, and reconnect the 2-P and 8-P connectors to the distributor cap. Make sure the two vacuum hoses going to the advance diaphragm are also plugged in to complete the installation. If you need to, you can test and adjust the timing of the motor before tightening the hold-down bolts on the distributor cap.
