What causes a car engine to have no spark?
A Bad Rotor Or Distributor Cap (cracks or carbon tracks that are allowing the spark to short to ground). Often the distributor cap is suspect. The internal and external surface of the cap should be clean. No erosion should be on the surface and the firing points should be free of rust or corrosion. Also, Confirm the rotor is in good working order.
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.
Can a bad ignition pickup cause an engine to stall?
One of the first symptoms of a bad ignition pickup is an engine that stalls and eventually will not restart. Consequently, An old or failing ignition pickup may cut out signal intermittently, which may cause the engine to stall. The engine may suddenly just shut off, almost as if the key had been turned off.

When do you need a spark plug wire set?
Signs that you may need spark plugs and wires include a Check Engine light, engine misfires, erratic idling, and increased emissions. New spark plugs and wires can also improve your fuel economy. O’Reilly Auto Parts carries ignition wire sets, spark plugs, and other ignition parts for most cars, trucks, and SUVs.
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,…
Where are the spark plugs on a General Motors engine?
The placement of each spark plug wire on the distributor cap is directly correlated to the engines firing order. For example; a standard V-8 General Motors engine has eight individual cylinders. However, each cylinder fires (or reaches top dead center) at a specific time for optimal engine efficiency.
Which is the best test for no start, no spark condition?
KOEC test is best used for diagnosing no start, no spark condition. Black=known good ground. KOEO, primary ignition voltage must be present to continue with test. Crank Engine and check for ICM switching at ignition coil while cranking. As ICM switches, primary voltage spikes can be seen. 25k ohms total resistance per wire.
What to do if your car has no spark?
Connected an inline spark tester to the ignition coil secondary lead, started the engine, and found the spark was intermittent. Used a multi-meter to measure the resistance of the ignition coil and found the measured resistance was within specifications.
Can a Kohler command 25 have no spark?
I had the same think happen on a Kohler Command 25 on a customers Z turn a few years ago. Shut off engine, let set few minutes, refused to restart, no fire on either plug. Cranked engine one more time, and one cylinder picked up fire, and then shortly the other one came back to life. Replaced both modules. Click to expand…
