Can a bad distributor cap cause a misfire?
The throttle body fuel injectors do not spray gasoline. The following are usually the most common symptoms of a bad spark plug wires, or a bad distributor cap and rotor on this type of GM distributor mounted ignition control module: The car (or truck, or mini-van, or van) starts and runs, but with a misfire.
What causes no spark at end of spark plug?
There are three specific components inside the distributor that may cause a lack of spark at the end of the spark plug to appear. A broken distributor cap Moisture or condensation inside the distributor cap Broken distributor rotor In order to diagnose the precise cause of the distributor failure,…
What are the symptoms of a bad ignition module?
The following are usually the most common symptoms of a bad spark plug wires, or a bad distributor cap and rotor on this type of GM distributor mounted ignition control module: The car (or truck, or mini-van, or van) starts and runs, but with a misfire. The check engine light is on. Lack of power.
Where is the spark in an ignition system?
Electronic ignition pickups are a component found on traditional electronic distributor ignition systems. They are located inside the distributor and function as the trigger for the ignition system to produce spark. The pickup coil monitors the rotation of the distributor and triggers the ignition system.
Is there no spark from distributor to spark plugs?
Q: No spark from distributor cap to spark plugs. Car died while driving. Wouldn’t start again. I did basic No start troubleshooting. Tested from the ignition coil to the distributor is good, from the cap itself no power. I replaced the cap, rotor, tfi, distributor itself, and the ignition coil. Same results.
Can a car run with a bad distributor cap?
Distributors play an important role in vehicle’s mechanism. Unfortunately, a car won’t run with a faulty distributor. It supports the engine’s distributing current, engine and connects the spark plugs to the ignition coil. However, bad distributor cap symptoms can come up anytime while driving.
Why is there no spark in my ignition?
An ignition module requires some type of external input in order to activate. If your vehicle stalls unexpectedly during operation and will not start again, it is likely because of loose or corroded electrical connections in the ignition module. In this case, check the switch, clean oxidized terminals, and replace broken wires if necessary.
How do you get spark from ignition coil?
High voltage is then generated in the coil windings. Voltage transformation produced by the interruption coincides to each spark generated. Older ignition systems used breaker points to interrupt the circuit, while more modern systems “sense” the need for spark by means of a hall-effect switch or crankshaft position sensor.

How does the GM distributor mounted ignition module work?
OK, once the fuel injection computer receives the Distributor Reference Hi Signal, it starts activating the fuel injectors and above 400 RPM, starts to send a 5 Volt Bypass Signal to the ignition control module. It’s with the Bypass Signal that the computer starts to retard and advance ignition timing with the IC Signal.
What does distributor reference Hi signal mean on ignition module?
This digital signal is called the: Distributor Reference Hi Signal in the majority of the service literature. Also, after receiving the pick up coil signal, the ignition control module starts to switch the primary current (of the ignition coil) On and Off.
