The distributor rotor and cap keep the distributor’s contents separate from the engine and keep the distributor’s working parts clean and tidy – while supporting the incredibly high volts of energy and delivering them to the appropriate spark plugs. The spark plugs utilize the spark from the distributor to ignite the fuel mixture,…

When do you need to replace spark plugs?

If you haven’t replaced the spark plug wires in more than three years, your wires may be worn. Also, check your car owner’s manual or vehicle repair manual for the interval schedule for the spark plugs. Your may need to service (gap check and adjustment) or replace the plugs.

How often does a spark plug spark on a pickup?

A lot could have gone wrong when installing the pickup coil. As a rule I always replaced the module and pickup together. If you remove the distributor, remove the coil wire from the cap and connect a spark plug to it, ground the distributor and with the key on spin the drive gear you should see the plug spark 4 times per rotation of the shaft.

How are spark plugs used to keep the engine running?

The spark plugs utilize the spark from the distributor to ignite the fuel mixture, which is what keeps the engine running. High voltage runs through this entire distributor system during the operation of your vehicle, but if there’s an issue this voltage won’t get distributed to the correct spark plugs to ensure that your engine will run.

How do you remove distributor cap on Dodge Ram?

How do you remove a spark plug from a distribitor?

Wiggling and slightly twisting the wire boots while pulling upwards will aid in removal. It is a good idea to trace the spark plug wires from each cylinder back to the distributor cap when labeling the wires. Now that the spark plug wires and coil wire are removed from the distribitor cap, the cap can be removed from the distributor.

How can I find out if my car has no spark?

Step 1: Scan the car to find the misfiring cylinders. Use a scan tool to find the diagnostic trouble code (DTC) numbers for the problem. If you do not have access to a scan tool, your local parts store can scan your car for free. Step 2: Get a printout with all the code numbers.

How can you tell if a spark plug is defective?

Gently drag the screwdriver down the length of each spark plug wire, around the coil, and the boots. Look for electrical arcs and listen for a snapping noise that may indicate a high-voltage electrical leak. If you see an electrical arc from the wire to the screwdriver, the wire is defective.

How does the computer connect to the fuel pump?

To activate the fuel pump the computer actually connects one of the ground wires to complete the circuit and send power to the fuel pump. The wire coming from the fuel pump is the other ground wire. Electrical wiring issues can be a nightmare if you don’t have the appropriate wiring diagrams to see which wires go to where.

How does a fuel pump relay get power?

The relay wires should have ground on two wires, power on one wire and switched power on another wire. To activate the fuel pump the computer actually connects one of the ground wires to complete the circuit and send power to the fuel pump.
