The distributor rotor and cap pass voltage from ignition coils into the engine’s cylinders. From here, the air/fuel mixture is ignited and powers the engine. The coil connects to the...
When your distributor cap or rotor goes bad you could be left stranded and unable to start your vehicle. The rotor is a whirling dervish of power distribution, transferring energy from the ignition...
The distributor is part of the ignition system in your vehicle and its purpose is to route high voltage from the ignition coil to the spark plug. The spark plug then...
The rotor exists to send power from your ignition coil over to your spark plugs – which make sure that your plugs ignite to start the fuel combustion process. Each time it goes...
The complicated process of a vehicle's ignition system requires precise timing on the part of the various systems involved. Starting a vehicle involves much more than just turning a key in the ignition...
In older cars, a distributor is one of the central parts of the ignition system. Since the early 1990's, many automakers have moved to using ignition systems without distributors. Though the number of cars with...
It is recommended to replace distributor cap and rotor at the same time you are having the spark plugs and spark plug wires replaced. The cap and rotor contacts will wear down just like the spark plug electrodes wear down...
Hi there. The ignition system for the 4.9L in your vehicle, should be HEI (high energy ignition) and does not have a CKP (crankshaft position sensor). The pick-up coil is inside the distributor and most likely is not the cause...
There is more than one manufacturer of distributors or its internal components and will operate the same way but have some small different changes that do not affect the performance of the part. You should not have any problems without...
Hi there. For the carburetor swap out, you will need to have a least a CFM of 850 or 950 for a big block GM engine. If you are concerned about fuel consumption, then you could do a CFM of...
Hi there. First you would need to know the firing order for the electronics on the distributor. The distributor number one on the firing order is the terminal on the right side at the front of the vehicle. Since you...
The distributor on the 1996 Accord has an integrated Cylinder Position (CYP) Sensor, Crankshaft Position Sensor (CKP) and Top Dead Center (TDC) Sensor. If you have replaced the distributor due to diagnostic trouble code P1382 setting, which involves faults with...
The most common cause of the engine crank no start is loss of ignition spark from the ignition system. The distributor is known to have internal shaft oil leaks that will short out the internal cam and crankshaft sensors and...
Hi there. It is possible that the distributor was off by one tooth. This is very common. I suggest removing the distributor, then removing the valve cover to the side that has number 1 cylinder (the valve cover that is...
You will need to take out one spark plug wire off a spark plug and put it near a ground with a screw driver or spark tester installed and crank engine to see if there is spark. If no spark...
Hi there. The distributor rotor should face the number one on the distributor with the number one cylinder on the compression stroke with both the rocker arms for the intake and exhaust valves shut. The back of the distributor has...
The Hall effect pick-up assembly in the distributor can be tested via the Factory Service Manual but that procedure has more than 15 steps. A more efficient test method is to use a self powered “indicator light” that is made...
Hi there. Check the spark plugs with a spark adapter tool to see if there is a park induced from the coil. If there is no spark, then the spark plug wires could be burned and need replaced. If the...
Hi There, This may be related to many different possibilities that may be contributing to a lack of spark. Things like ignition coils, crankshaft position sensor, spark plugs, spark plug wires or ignition module are all components that help to...
Your vehicle is equipped with a crankshaft position sensor. That sensor is on the primary side of the ignition circuit and consequently you should test the sensor and all wiring to the distributor to be sure it is functioning. If...
Check the ignition timing on the distributor and see if the timing is off. If the timing is good, then the accelerator pump in the carburetor or the fuel injectors are not working properly (if your vehicle has TBI injection)....
Check all the ignition system primary circuit electrical connections to the distributor and test the coil and the distributor. Be sure all electrical connections were restored and are secure. It is possible that an electrical connector was just left disconnected,...
Hello, It sounds like you may have a bad fuel pressure regulator or potentially a leaking or faulty fuel injector. I would suggest having an expert from YourMechanic come to your location to run a fuel pressure test to determine...
Hello, thank you for writing in. The first two components to look at are the distributor and the coil. If you have a spark tester, test light, or voltmeter, you can measure the power supply along the circuit and find...
If you are using the marks on the harmonic balancer to find TDC, occasionally the balancer will have shifted (the rubber bond breaks) causing the timing mark to be some degrees off. Consequently, the crankshaft is not really at TDC...
Hello - "crossed spark plug wires" means simply that your plug wires are not attached to the plugs and/or the distributor in the correct firing order. Your cylinders are numbered 1 to 6, front to rear on your engine. The...
