Where does the ignition coil go in a wasted spark system?
In the wasted spark system, a single contact is used for two leads, but each lead connects one cylinder. In General motors where high energy ignition (HEI) system used, there is no central post in the distributor cap. The ignition coil is placed on the top of the distributor.
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.
What should spark reading be on ignition coil?
If your coil reads under 11.00, then chances are pretty good that this is the reason you’re not getting any spark or a very weak one. Replace the coil with a good quality new one, make sure you attach and tighten the leads correctly, plug in the top cable that goes to the distributor, turn the key and you should be good to go!
What happens when the distributor cap is not on?
Car doesn’t start. When the distributor cap isn’t on tightly or is malfunctioning, the engine is unable to send the spark through the entire circuit required to move the cylinders – which ultimately make the car run.
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 distributor rotor and cap work?
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,…
What happens if there is no external signal to the ignition coil?
With no external signal to the coil negative primary post, voltage would travel through the ignition coil windings without inducing any secondary spark. A switch, or signaling device, triggers an interruption in the circuit.
